This operationally simple transformation allows for the introduction of not only well-established CF3 and CF2H groups, but also the synthetically (and medicinally) underexplored CF2Cl and CFClH motifs—thereby broadening access to previously inaccessible chemical space of halogenated amine scaffolds. The method displays broad substrate scope and functional-group tolerance while operating under mild conditions. Late-stage functionalization of drug-like derivatives of Oxaprozin, Erlotinib, and Ibuprofen (among others) is reported. acknowledgement: "Funded by the European Union (ERC, C-HANCE, 101142915 to N.M.).

Disequilibration by sensitization of azobenzene under confinement (DESC) has recently emerged as a supramolecular strategy to bypass this limitation without the need to derivatize the azobenzene scaffold. Here, we expand DESC to water-soluble azopolymers obtained by RAFT polymerization and systematically investigate the interplay between the polymer structure and DESC efficiency. Using this approach, we achieved as much as 85% of the direct photoexcitation (UV) switching efficiency, while utilizing low-energy (yellow) light. These results establish general design principles for combining DESC with polymeric systems, opening new opportunities for the development of functional materials driven with low-energy light. acknowledgement: "This work is supported by the European Research Council (Consolidator Grand project MULTIMODAL, no. 101045223), the Research Council of Finland Center of Excellence “Life-Inspired Hybrid Materials Research” (LIBER, no. 346107) and the Research Council of Finland Flagship Programme on Photonics Research and Innovation (PREIN, no. 320165).

One material where the species transferred seems more certain is ionomers, i.e., polymers that contain mobile ions balanced by fixed counter‐charges. When ionomers touch a neutral surface, the latter becomes charged in the sign of the mobile ion, strongly suggesting ion transfer. However, the mechanism and governing factors of transfer remain poorly understood. Here, we demonstrate that binding affinity between mobile ion and ionomer controls charge transfer with ionomers. We use ionomers with fixed anions and cations and perform ion exchange to create samples with a series of transferrable ions. We observe a strong binding‐affinity dependence for the anionic ionomer, such that mobile cations with the highest affinity transfers the least charge. Weaker, yet clear dependence was measured for the cationic ionomer, which follows the hydration free energy of the mobile anion. Using inductively coupled plasma optical emission spectroscopy (ICP‐OES), we confirm transfer of the mobile ions to the counter sample's surface. Our results confirm the identify and mechanism of charge transfer with ionomeric materials, with potential implications for contact electrification more broadly. acknowledged_ssus: - _id: LifeSc acknowledgement: "This research was supported by the Scientific Service Units (SSU) of IST-Austria through resources provided by the Lab Support Facility (LSF).\r\nOpen Access funding provided by Institute of Science and Technology Austria." article_number: e5487708 article_processing_charge: Yes (via OA deal) article_type: original author: - first_name: John R full_name: Hoffman Jr, John R id: 0cf4072c-94e2-11ee-bdf9-90a13138901e last_name: Hoffman Jr - first_name: Stefan Alexander full_name: Freunberger, Stefan Alexander id: A8CA28E6-CE23-11E9-AD2D-EC27E6697425 last_name: Freunberger orcid: 0000-0003-2902-5319 - first_name: Scott R full_name: Waitukaitis, Scott R id: 3A1FFC16-F248-11E8-B48F-1D18A9856A87 last_name: Waitukaitis orcid: 0000-0002-2299-3176 citation: ama: 'Hoffman Jr JR, Freunberger SA, Waitukaitis SR.

Methods were developed to synthesize natural/non‐natural chimeric molecules combining foldamer and DNA segments. The ability of the linker to position the foldamer helix and the duplex DNA so that their rims and grooves are in register, despite their completely different chemical nature, was demonstrated using single crystal X‐ray diffraction, circular dichroism and molecular models. Bio‐layer interferometry confirmed that artificial hairpin DNA duplexes keep their ability to bind to DNA binding proteins. The chimeric molecules may pave the way to competitive inhibitors of protein‐DNA interactions involving sequence‐selective DNA‐binding proteins. article_number: e202505273 article_processing_charge: Yes (in subscription journal) article_type: original author: - first_name: Manuel full_name: Loos, Manuel last_name: Loos - first_name: Felix full_name: Xu, Felix last_name: Xu - first_name: Pradeep K full_name: Mandal, Pradeep K id: 6a3def15-d4b4-11ef-9fa9-a24c1f545ec3 last_name: Mandal orcid: 0000-0001-5996-956X - first_name: Tulika full_name: Chakrabortty, Tulika last_name: Chakrabortty - first_name: Céline full_name: Douat, Céline last_name: Douat - first_name: David B. full_name: Konrad, David B. last_name: Konrad - first_name: Melis full_name: Cabbar, Melis last_name: Cabbar - first_name: Johannes full_name: Singer, Johannes last_name: Singer - first_name: Valentina full_name: Corvaglia, Valentina last_name: Corvaglia - first_name: Thomas full_name: Carell, Thomas last_name: Carell - first_name: Ivan full_name: Huc, Ivan last_name: Huc citation: ama: Loos M, Xu F, Mandal PK, et al.

Chemical changes that occur during each one of these steps render them performance determining. Particularly the purification steps, bypassed in conventional solid-state synthesis, are the cause for large discrepancies among similar solution-processed materials. In present work, the investigation focuses on a water-based surfactant free solution synthesis of SnSe, a highly relevant thermoelectric material. We show and rationalize that the number of leaching steps, purification solvent, annealing, and annealing atmosphere have significant influence on the Sn : Se ratio and impurity content in the powder. Such compositional changes that are undetectable by conventional characterization techniques lead to distinct consolidated materials with different types and concentration of defects. Additionally, the profound effect on their transport properties is demonstrated. We emphasize that understanding the chemistry and identifying key chemical species and their role throughout the process is paramount for optimizing material performance. Furthermore, we aim to demonstrate the necessity of comprehensive reporting of these steps as a standard practice to ensure material reproducibility. acknowledged_ssus: - _id: EM-Fac - _id: NMR - _id: LifeSc acknowledgement: ISTA and the Werner Siemens Foundation financially supported this work.

From the initial use of carbonate electrolytes, that were then found to be entirely unsuitable, to the belief that (su)peroxide was solely responsible for degradation, before the more reactive singlet oxygen was found to form, to the hypothesis that capacity depends on a competing surface/solution mechanism before a practically exclusive solution mechanism was identified. Herein, we argue for an ever-fresh look at the reported data without bias towards supposedly established explanations. We explain how the latest findings on rate and capacity limits, as well as the origin of side reactions, are connected via the disproportionation (DISP) step in the (dis)charge mechanism. Therefrom, directions emerge for the design of electrolytes and mediators on how to suppress side reactions and to enable high rate and high reversible capacity. acknowledgement: S.A.F. is indebted to ISTA for support.

In particular, the design of photochemically triggered-orthogonal systems integrated into solid materials that enable multiple dynamic control over their properties remains a longstanding challenge. Here, we report the orthogonal and reversible control of two types of photoswitches in an integrated solid porous framework, that is, visible-light responsive o-fluoroazobenzene and nitro-spiropyran motifs. The properties of the constructed material can be selectively controlled by different wavelengths of light thus generating four distinct states providing a basis for dynamic multifunctional materials. Solid-state NMR spectroscopy demonstrated the selective transformation of the azobenzene switch in the bulk, which in turn modulates N2 and CO2 adsorption. acknowledgement: 'This work was supported from the following sources: China Scholarship Council (CSC PhD Fellowship No. 201808330459 to J.S.), the Ministry of Education, Culture and Science of the Netherlands (Gravitation Program No. 024.001.035 to BLF), Financial support from The Netherlands Organization for Scientific Research (NWO-CW), the European Research Council (ERC; advanced Grant No. 694345 to B.L.F.).

A collection of carbonaceous materials with different pore networks and high nitrogen content was characterized and used to catalyze four reactions to deduce structure–activity relationships. The CO2 cycloaddition and Knoevenagel reaction depend on Lewis basic sites (electron-rich nitrogen species). The absence of large conjugated carbon domains resulting from the introduction of large amounts of nitrogen in the carbon network is responsible for poor redox activity, as observed through the catalytic reduction of nitrobenzene with hydrazine and the catalytic oxidation of 3,3′,5,5′-tetramethylbenzidine using hydroperoxide. The material with the highest activity towards Lewis acid catalysis (in the hydrolysis of (dimethoxymethyl)benzene to benzaldehyde) is the most effective for small molecule activation and presents the highest concentration of electron-poor nitrogen species. article_number: e202211663 article_processing_charge: No article_type: original author: - first_name: Enrico full_name: Lepre, Enrico last_name: Lepre - first_name: Sylvain full_name: Rat, Sylvain last_name: Rat - first_name: Cristian full_name: Cavedon, Cristian last_name: Cavedon - first_name: Peter H. full_name: Seeberger, Peter H. last_name: Seeberger - first_name: Bartholomäus full_name: Pieber, Bartholomäus id: 93e5e5b2-0da6-11ed-8a41-af589a024726 last_name: Pieber orcid: 0000-0001-8689-388X - first_name: Markus full_name: Antonietti, Markus last_name: Antonietti - first_name: Nieves full_name: López‐Salas, Nieves last_name: López‐Salas citation: ama: Lepre E, Rat S, Cavedon C, et al.

These sequences exclusively assemble as antiparallel duplexes. The modification of the duplex inner rim by varying the nature of the substituents borne by the aromatic monomers allowed us to identify sequences that can hybridize by combining two chemically different strands, with high affinity and complete selectivity in water. X‐ray crystallography confirmed the expected antiparallel configuration of the duplexes whereas NMR spectroscopy and mass spectrometry allowed us to assess precisely the extent of the hybridization. The hybridization kinetics of the aromatic strands was shown to depend on both the nature of the substituents responsible for strand complementarity and the length of the aromatic strand. These results highlight the great potential of aromatic hetero‐duplex as a tool to construct non‐symmetrical dynamic supramolecular assemblies. article_number: e202311639 article_processing_charge: Yes (in subscription journal) article_type: original author: - first_name: Victor full_name: Koehler, Victor last_name: Koehler - first_name: Gabrielle full_name: Bruschera, Gabrielle last_name: Bruschera - first_name: Eric full_name: Merlet, Eric last_name: Merlet - first_name: Pradeep K full_name: Mandal, Pradeep K id: 6a3def15-d4b4-11ef-9fa9-a24c1f545ec3 last_name: Mandal orcid: 0000-0001-5996-956X - first_name: Estelle full_name: Morvan, Estelle last_name: Morvan - first_name: Frédéric full_name: Rosu, Frédéric last_name: Rosu - first_name: Céline full_name: Douat, Céline last_name: Douat - first_name: Lucile full_name: Fischer, Lucile last_name: Fischer - first_name: Ivan full_name: Huc, Ivan last_name: Huc - first_name: Yann full_name: Ferrand, Yann last_name: Ferrand citation: ama: Koehler V, Bruschera G, Merlet E, et al.

The manufacturing and processing of these materials have been widely explored with mechanical alignment establishing itself as a preferred method due to its ease of use and widespread applicability. However, the fundamental chemistry behind the required two‐step polymerization for mechanical alignment has limitations in both fabrication and substrate compatibility. In this work we introduce a new protection‐deprotection approach utilizing a two‐stage Diels–Alder cyclopentadiene‐maleimide step‐growth polymerization to enable mild yet efficient, fast, controlled, reproducible and user‐friendly polymerizations, broadening the scope of liquid crystal systems. Thorough characterization of the films by DSC, DMA, POM and WAXD show the successful synthesis of a uniaxially aligned liquid crystal network with thermomechanical actuation abilities. article_number: e202214339 article_processing_charge: No article_type: original author: - first_name: Jesus full_name: Guillen Campos, Jesus last_name: Guillen Campos - first_name: Friedrich J full_name: Stricker, Friedrich J id: 7aca2cfc-46cf-11f0-abd3-8c96b5186745 last_name: Stricker - first_name: Kyle D. full_name: Clark, Kyle D. last_name: Clark - first_name: Minwook full_name: Park, Minwook last_name: Park - first_name: Sophia J. full_name: Bailey, Sophia J. last_name: Bailey - first_name: Alexa S. full_name: Kuenstler, Alexa S. last_name: Kuenstler - first_name: Ryan C. full_name: Hayward, Ryan C. last_name: Hayward - first_name: Javier full_name: Read de Alaniz, Javier last_name: Read de Alaniz citation: ama: Guillen Campos J, Stricker FJ, Clark KD, et al.

By studying a pair of structurally homologous cross-β amyloid fibrils, HET-s and HELLF, with a specific isotope-labeling approach and magic-angle-spinning (MAS) NMR, we have characterized the dynamic behavior of Phe and Tyr aromatic rings to show that the hydrophobic amyloid core is rigid, without any sign of "breathing motions" over hundreds of milliseconds at least. Aromatic residues exposed at the fibril surface have a rigid ring axis but undergo ring flips, on a variety of time scales from ns to µs. Our approach provides direct insight into hydrophobic-core motions, enabling a better evaluation of the conformational heterogeneity generated from a NMR structural ensemble of such amyloid cross-β architecture. acknowledgement: We thank AlbertA.

Using the myriad of such building blocks, a broad spectrum of functionalities has been applied for COF syntheses for broad applications, including heterogeneous catalysis. Herein, we report the synthesis of a new family of porous and crystalline COFs using a novel acridine linker and benzene-1,3,5-tricarbaldehyde derivatives bearing a variable number of hydroxy groups. With the broad absorption in the visible light region, the COFs were applied as photocatalysts in metallaphotocatalytic C−N cross-coupling. The fully β-ketoenamine linked COF showed the highest activity, due to the increased charge separation upon irradiation. The COF showed good to excellent yields for several aryl bromides, good recyclability and even catalyzed the organic transformation in presence of green light as energy source. article_number: e202117738 article_processing_charge: No article_type: original author: - first_name: Michael full_name: Traxler, Michael last_name: Traxler - first_name: Sebastian full_name: Gisbertz, Sebastian last_name: Gisbertz - first_name: Pradip full_name: Pachfule, Pradip last_name: Pachfule - first_name: Johannes full_name: Schmidt, Johannes last_name: Schmidt - first_name: Jérôme full_name: Roeser, Jérôme last_name: Roeser - first_name: Susanne full_name: Reischauer, Susanne last_name: Reischauer - first_name: Jabor full_name: Rabeah, Jabor last_name: Rabeah - first_name: Bartholomäus full_name: Pieber, Bartholomäus id: 93e5e5b2-0da6-11ed-8a41-af589a024726 last_name: Pieber orcid: 0000-0001-8689-388X - first_name: Arne full_name: Thomas, Arne last_name: Thomas citation: ama: Traxler M, Gisbertz S, Pachfule P, et al.

The RNA molecule is far too complex to have formed in one evolutionary step, suggesting that ancestral proto-RNAs (first ancestor of RNA) may have existed, which evolved over time into the RNA of today. Here we show that isoxazole nucleosides, which are quickly formed from hydroxylamine, cyanoacetylene, urea and ribose, are plausible precursors for RNA. The isoxazole nucleoside can rearrange within an RNA-strand to give cytidine, which leads to an increase of pairing stability. If the proto-RNA contains a canonical seed-nucleoside with defined stereochemistry, the seed-nucleoside can control the configuration of the anomeric center that forms during the in-RNA transformation. The results demonstrate that RNA could have emerged from evolutionarily primitive precursor isoxazole ribosides after strand formation. acknowledgement: We thank Stefan Wiedemann for the synthesis of reference compounds and Pia Heinrichs for assistance in the NMR measurements of the oligonucleotides.

The activation of this precatalyst towards cross-coupling reactions follows a hitherto undisclosed mechanism that is different from previously reported light-responsive nickel complexes that undergo metal-to-ligand charge transfer. Theoretical and spectroscopic investigations revealed that irradiation of Ni(Czbpy)Cl2 with visible light causes an initial intraligand charge transfer event that triggers productive catalysis. Ligand polymerization affords a porous, recyclable organic polymer for heterogeneous nickel catalysis of cross-coupling reactions. The heterogeneous catalyst shows stable performance in a packed-bed flow reactor during a week of continuous operation. article_number: e202211433 article_processing_charge: No article_type: original author: - first_name: Cristian full_name: Cavedon, Cristian last_name: Cavedon - first_name: Sebastian full_name: Gisbertz, Sebastian last_name: Gisbertz - first_name: Susanne full_name: Reischauer, Susanne last_name: Reischauer - first_name: Sarah full_name: Vogl, Sarah last_name: Vogl - first_name: Eric full_name: Sperlich, Eric last_name: Sperlich - first_name: John H. full_name: Burke, John H. last_name: Burke - first_name: Rachel F. full_name: Wallick, Rachel F. last_name: Wallick - first_name: Stefanie full_name: Schrottke, Stefanie last_name: Schrottke - first_name: Wei‐Hsin full_name: Hsu, Wei‐Hsin last_name: Hsu - first_name: Lucia full_name: Anghileri, Lucia last_name: Anghileri - first_name: Yannik full_name: Pfeifer, Yannik last_name: Pfeifer - first_name: Noah full_name: Richter, Noah last_name: Richter - first_name: Christian full_name: Teutloff, Christian last_name: Teutloff - first_name: Henrike full_name: Müller‐Werkmeister, Henrike last_name: Müller‐Werkmeister - first_name: Dario full_name: Cambié, Dario last_name: Cambié - first_name: Peter H. full_name: Seeberger, Peter H. last_name: Seeberger - first_name: Josh full_name: Vura‐Weis, Josh last_name: Vura‐Weis - first_name: Renske M. full_name: van der Veen, Renske M. last_name: van der Veen - first_name: Arne full_name: Thomas, Arne last_name: Thomas - first_name: Bartholomäus full_name: Pieber, Bartholomäus id: 93e5e5b2-0da6-11ed-8a41-af589a024726 last_name: Pieber orcid: 0000-0001-8689-388X citation: ama: Cavedon C, Gisbertz S, Reischauer S, et al.

The nature and structure of the dimers was evidenced by 2D NOESY and DOSY spectroscopy, mass spectrometry and X‐ray crystallography. The binding interface involves a large hydrophobic aromatic surface and hydrogen bonding. Dimerization requires that helices have the same handedness and the presence of a C‐terminal carboxy function. The protonation state of the carboxy group plays a crucial role, resulting in pH dependence of the association. Dimerization is also influenced by neighboring side chains and can be programmed to selectively produce heteromeric aggregates. article_number: e202116509 article_processing_charge: No article_type: original author: - first_name: Daniel full_name: Bindl, Daniel last_name: Bindl - first_name: Pradeep K full_name: Mandal, Pradeep K id: 6a3def15-d4b4-11ef-9fa9-a24c1f545ec3 last_name: Mandal orcid: 0000-0001-5996-956X - first_name: Lars full_name: Allmendinger, Lars last_name: Allmendinger - first_name: Ivan full_name: Huc, Ivan last_name: Huc citation: ama: Bindl D, Mandal PK, Allmendinger L, Huc I.

One possibility is employing surfactant-free solution synthesis to produce nanopowders. We propose the strategy of functionalizing “naked” particles’ surface by inorganic molecules to control the nanostructure and, consequently, thermoelectric performance. In particular, we use bismuth thiolates to functionalize surfactant-free SnTe particles’ surfaces. Upon thermal processing, bismuth thiolates decomposition renders SnTe-Bi2S3 nanocomposites with synergistic functions: 1) carrier concentration optimization by Bi doping; 2) Seebeck coefficient enhancement and bipolar effect suppression by energy filtering; and 3) lattice thermal conductivity reduction by small grain domains, grain boundaries and nanostructuration. Overall, the SnTe-Bi2S3 nanocomposites exhibit peak z T up to 1.3 at 873 K and an average z T of ≈0.6 at 300–873 K, which is among the highest reported for solution-processed SnTe.' acknowledged_ssus: - _id: EM-Fac - _id: NanoFab acknowledgement: This research was supported by the Scientific Service Units (SSU) of IST Austria through resources provided by Electron Microscopy Facility (EMF) and the Nanofabrication Facility (NNF).

Here, we first obtain phase-pure, colloidally stable nanocubes. Second, we elucidate the pathway by which copper(II) nitrate and oleylamine form Cu3N. We find that oleylamine is both a reductant and a nitrogen source. Oleylamine is oxidized by nitrate to a primary aldimine, which reacts further with excess oleylamine to a secondary aldimine, eliminating ammonia. Ammonia reacts with CuI to form Cu3N. Third, we investigated the surface chemistry and find a mixed ligand shell of aliphatic amines and carboxylates (formed in situ). While the carboxylates appear tightly bound, the amines are easily desorbed from the surface. Finally, we show that doping with palladium decreases the band gap and the material becomes semi-metallic. These results bring insight into the chemistry of metal nitrides and might help the development of other metal nitride nanocrystals. acknowledgement: 'J.D.R. and M.P. acknowledge the SNF Eccellenza funding scheme (project number: 194172).

Here we show that the redox potential of a carbon nitride photocatalyst (CN-OA-m) can be tuned by changing the irradiation wavelength to generate electron holes with different oxidation potentials. This tuning was the key to realizing photo-chemo-enzymatic cascades that give either the (S)- or the (R)-enantiomer of phenylethanol. In combination with an unspecific peroxygenase from Agrocybe aegerita, green light irradiation of CN-OA-m led to the enantioselective hydroxylation of ethylbenzene to (R)-1-phenylethanol (99 % ee). In contrast, blue light irradiation triggered the photocatalytic oxidation of ethylbenzene to acetophenone, which in turn was enantioselectively reduced with an alcohol dehydrogenase from Rhodococcus ruber to form (S)-1-phenylethanol (93 % ee). article_processing_charge: No article_type: original author: - first_name: Luca full_name: Schmermund, Luca last_name: Schmermund - first_name: Susanne full_name: Reischauer, Susanne last_name: Reischauer - first_name: Sarah full_name: Bierbaumer, Sarah last_name: Bierbaumer - first_name: Christoph K. full_name: Winkler, Christoph K. last_name: Winkler - first_name: Alba full_name: Diaz‐Rodriguez, Alba last_name: Diaz‐Rodriguez - first_name: Lee J. full_name: Edwards, Lee J. last_name: Edwards - first_name: Selin full_name: Kara, Selin last_name: Kara - first_name: Tamara full_name: Mielke, Tamara last_name: Mielke - first_name: Jared full_name: Cartwright, Jared last_name: Cartwright - first_name: Gideon full_name: Grogan, Gideon last_name: Grogan - first_name: Bartholomäus full_name: Pieber, Bartholomäus id: 93e5e5b2-0da6-11ed-8a41-af589a024726 last_name: Pieber orcid: 0000-0001-8689-388X - first_name: Wolfgang full_name: Kroutil, Wolfgang last_name: Kroutil citation: ama: Schmermund L, Reischauer S, Bierbaumer S, et al.

However, rendering DNA-based systems responsive to light has remained challenging. Herein, we describe the remote manipulation of native (non-photoresponsive) chiral plasmonic molecules (CPMs) using light. Our strategy is based on the use of a photoresponsive medium comprising a merocyanine-based photoacid. Upon exposure to visible light, the medium decreases its pH, inducing the formation of DNA triplex links, leading to a spatial reconfiguration of the CPMs. The process can be reversed simply by turning the light off and it can be repeated for multiple cycles. The degree of the overall chirality change in an ensemble of CPMs depends on the CPM fraction undergoing reconfiguration, which, remarkably, depends on and can be tuned by the intensity of incident light. Such a dynamic, remotely controlled system could aid in further advancing DNA-based devices and nanomaterials. article_processing_charge: No article_type: original author: - first_name: Joonas full_name: Ryssy, Joonas last_name: Ryssy - first_name: Ashwin K. full_name: Natarajan, Ashwin K. last_name: Natarajan - first_name: Jinhua full_name: Wang, Jinhua last_name: Wang - first_name: Arttu J. full_name: Lehtonen, Arttu J. last_name: Lehtonen - first_name: Minh‐Kha full_name: Nguyen, Minh‐Kha last_name: Nguyen - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn - first_name: Anton full_name: Kuzyk, Anton last_name: Kuzyk citation: ama: Ryssy J, Natarajan AK, Wang J, et al.
