However, moving beyond simple binary responses necessitates the introduction of new elements that control the chemistry of the photoswitching process at the molecular scale. To achieve this goal, we designed, synthesized and developed a single photochrome, based on a modified donor–acceptor Stenhouse adduct (DASA), capable of independently addressing multiple molecular states. The multi-stage photoswitch enables complex switching phenomena. To demonstrate this, we show spatial control of the transformation of a three-stage photoswitch by tuning the population of intermediates along the multi-step reaction pathway of the DASAs without interfering with either the first or final stage. This allows for a photonic three-stage logic gate where the secondary wavelength solely negates the input of the primary wavelength. These results provide a new strategy to move beyond traditional on/off binary photochromic systems and enable the design of future molecular logic systems.","lang":"eng"}],"_id":"21819","external_id":{"pmid":["35681046"]},"quality_controlled":"1","date_updated":"2026-05-18T09:13:44Z","intvolume":"        14","date_published":"2022-06-09T00:00:00Z","pmid":1,"publication":"Nature Chemistry","article_processing_charge":"No","scopus_import":"1","doi":"10.1038/s41557-022-00947-8","fulldoi":"https://doi.org/10.1038/s41557-022-00947-8","date_created":"2026-05-06T10:56:14Z","article_type":"original","publication_status":"published","year":"2022","type":"journal_article","author":[{"full_name":"Stricker, Friedrich J","id":"7aca2cfc-46cf-11f0-abd3-8c96b5186745","first_name":"Friedrich J","last_name":"Stricker"},{"last_name":"Sanchez","first_name":"David M.","full_name":"Sanchez, David M."},{"last_name":"Raucci","first_name":"Umberto","full_name":"Raucci, Umberto"},{"first_name":"Neil D.","full_name":"Dolinski, Neil D.","last_name":"Dolinski"},{"last_name":"Zayas","full_name":"Zayas, Manuel S.","first_name":"Manuel S."},{"last_name":"Meisner","full_name":"Meisner, Jan","first_name":"Jan"},{"last_name":"Hawker","full_name":"Hawker, Craig.

A key advantage is their ability to exhibit quasi-metallic transport, in contrast to conjugated molecular wires which typically exhibit a low conductance that decays as the wire length increases. Here, we study a family of oligophenylene-bridged bis(triarylamines) with tunable and stable mono- or di-radicaloid character. These wires can undergo one- and two-electron chemical oxidations to the corresponding mono-cation and di-cation, respectively. We show that the oxidized wires exhibit reversed conductance decay with increasing length, consistent with the expectation for Su–Schrieffer–Heeger-type one-dimensional topological insulators. The 2.6-nm-long di-cation reported here displays a conductance greater than 0.1G0, where G0 is the conductance quantum, a factor of 5,400 greater than the neutral form. The observed conductance–length relationship is similar between the mono-cation and di-cation series. Density functional theory calculations elucidate how the frontier orbitals and delocalization of radicals facilitate the observed non-classical quasi-metallic behaviour."}],"oa_version":"None","publication":"Nature Chemistry","pmid":1,"date_published":"2022-07-07T00:00:00Z","intvolume":"        14","date_updated":"2024-12-10T09:37:45Z","quality_controlled":"1","year":"2022","article_type":"original","publication_status":"published","date_created":"2024-09-06T13:05:31Z","fulldoi":"https://doi.org/10.1038/s41557-022-00978-1","doi":"10.1038/s41557-022-00978-1","scopus_import":"1","article_processing_charge":"No"},{"title":"Electrostatic co-assembly of nanoparticles with oppositely charged small molecules into static and dynamic superstructures","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","extern":"1","month":"10","day":"01","status":"public","keyword":["General Chemical Engineering","General Chemistry"],"abstract":[{"text":"Coulombic interactions can be used to assemble charged nanoparticles into higher-order structures, but the process requires oppositely charged partners that are similarly sized. The ability to mediate the assembly of such charged nanoparticles using structurally simple small molecules would greatly facilitate the fabrication of nanostructured materials and harnessing their applications in catalysis, sensing and photonics. Here we show that small molecules with as few as three electric charges can effectively induce attractive interactions between oppositely charged nanoparticles in water. These interactions can guide the assembly of charged nanoparticles into colloidal crystals of a quality previously only thought to result from their co-crystallization with oppositely charged nanoparticles of a similar size. Transient nanoparticle assemblies can be generated using positively charged nanoparticles and multiply charged anions that are enzymatically hydrolysed into mono- and/or dianions.

Redox mediators are recognized to be key for improving rechargeability. However, it is unclear how they affect 1O2 formation, which hinders strategies for their improvement. Here we clarify the mechanism of mediated peroxide and superoxide oxidation and thus explain how redox mediators either enhance or suppress 1O2 formation. We show that charging commences with peroxide oxidation to a superoxide intermediate and that redox potentials above ~3.5 V versus Li/Li+ drive 1O2 evolution from superoxide oxidation, while disproportionation always generates some 1O2. We find that 1O2 suppression requires oxidation to be faster than the generation of 1O2 from disproportionation. Oxidation rates decrease with growing driving force following Marcus inverted-region behaviour, establishing a region of maximum rate."}],"external_id":{"isi":["000629296400001"],"pmid":["33723377"]},"intvolume":"        13","quality_controlled":"1","date_updated":"2024-10-09T21:00:28Z","pmid":1,"publication":"Nature Chemistry","date_published":"2021-03-15T00:00:00Z","doi":"10.1038/s41557-021-00643-z","fulldoi":"https://doi.org/10.1038/s41557-021-00643-z","scopus_import":"1","article_processing_charge":"No","year":"2021","article_type":"original","publication_status":"published","date_created":"2021-03-16T11:12:20Z"},{"citation":{"ieee":"C.

When using a single building block, self-assembly generally yields symmetrical objects in which all the subunits relate similarly to their neighbours. Here we report the discovery of a family of self-constructing cyclic macromolecules with stable folded conformations of low symmetry, which include some with a prime number (13, 17 and 23) of units, despite being formed from a single component. The formation of these objects amounts to the production of polymers with a perfectly uniform length. Design rules for the spontaneous emergence of such macromolecules include endowing monomers with a strong potential for non-covalent interactions that remain frustrated in competing entropically favoured yet conformationally restrained smaller cycles. The process can also be templated by a guest molecule that itself has an asymmetrical structure, which paves the way to molecular imprinting techniques at the level of single polymer chains."}],"_id":"21084","external_id":{"pmid":["33219361 "]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Emergence of low-symmetry foldamers from single monomers","extern":"1","OA_type":"green","OA_place":"repository","has_accepted_license":"1","status":"public","month":"11","day":"20","doi":"10.1038/s41557-020-00565-2","fulldoi":"https://doi.org/10.1038/s41557-020-00565-2","article_processing_charge":"No","year":"2020","article_type":"original","date_created":"2026-01-29T15:32:38Z","publication_status":"published","intvolume":"        12","date_updated":"2026-02-23T11:46:11Z","quality_controlled":"1","pmid":1,"publication":"Nature Chemistry","date_published":"2020-11-20T00:00:00Z"},{"publication_identifier":{"issn":["1755-4330"],"eissn":["1755-4349"]},"volume":12,"acknowledgement":"We acknowledge support from Peterhouse (T.C.T.M.), the Swiss National Science foundation (T.C.T.M.), the Royal Society (A.Š.), the Academy of Medical Sciences (A.Š.), the UCL Institute for the Physics of Living Systems (S.C.), Sidney Sussex College (G.M.), the Wellcome Trust (A.Š., M.V., C.M.D. and T.P.J.K.), the Schiff Foundation (A.J.D.), the Cambridge Centre for Misfolding Diseases (M.V., C.M.D. and T.P.J.K.), the BBSRC (C.M.D. and T.P.J.K.), the Frances and Augustus Newman Foundation (T.P.J.K.), the Swedish Research Council (S.L.) and the ERC grant MAMBA (S.L., agreement no. 340890).

By developing a general approach that combines theory, experiment and simulation, we reveal, in molecular detail, the mechanisms of Aβ42 oligomer dynamics during amyloid fibril formation. Even though all mature amyloid fibrils must originate as oligomers, we found that most Aβ42 oligomers dissociate into their monomeric precursors without forming new fibrils. Only a minority of oligomers converts into fibrillar structures. Moreover, the heterogeneous ensemble of oligomeric species interconverts on timescales comparable to those of aggregation. Our results identify fundamentally new steps that could be targeted by therapeutic interventions designed to combat protein misfolding diseases.","lang":"eng"}],"_id":"10351","oa_version":"None","external_id":{"pmid":["32303714"]},"title":"Dynamics of oligomer populations formed during the aggregation of Alzheimer’s Aβ42 peptide","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","extern":"1","month":"04","related_material":{"link":[{"relation":"erratum","url":"https://doi.org/10.1038/s41557-020-0468-6"}]},"day":"13","status":"public","keyword":["general chemical engineering","general chemistry"]},{"date_updated":"2024-12-11T08:00:35Z","quality_controlled":"1","intvolume":"        11","date_published":"2019-04-01T00:00:00Z","publication":"Nature Chemistry","pmid":1,"article_processing_charge":"No","scopus_import":"1","fulldoi":"https://doi.org/10.1038/s41557-019-0216-y","doi":"10.1038/s41557-019-0216-y","date_created":"2024-09-09T07:48:03Z","publication_status":"published","article_type":"original","year":"2019","OA_type":"closed access","extern":"1","title":"Non-chemisorbed gold–sulfur binding prevails in self-assembled monolayers","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"04","day":"01","status":"public","abstract":[{"text":"Gold–thiol contacts are ubiquitous across the physical and biological sciences in connecting organic molecules to surfaces. When thiols bind to gold in self-assembled monolayers (SAMs) the fate of the hydrogen remains a subject of profound debate—with implications for our understanding of their physical properties, spectroscopic features and formation mechanism(s). Exploiting measurements of the transmission through a molecular junction, which is highly sensitive to the nature of the molecule–electrode contact, we demonstrate here that the nature of the gold–sulfur bond in SAMs can be probed via single-molecule conductance measurements. Critically, we find that SAM measurements of dithiol-terminated molecular junctions yield a significantly lower conductance than solution measurements of the same molecule. Through numerous control experiments, conductance noise analysis and transport calculations based on density functional theory, we show that the gold–sulfur bond in SAMs prepared from the solution deposition of dithiols does not have chemisorbed character, which strongly suggests that under these widely used preparation conditions the hydrogen is retained.","lang":"eng"}],"_id":"17922","oa_version":"None","external_id":{"pmid":["30833721"]},"publisher":"Springer Nature","page":"351-358","language":[{"iso":"eng"}],"volume":11,"publication_identifier":{"issn":["1755-4330"],"eissn":["1755-4349"]},"issue":"4","type":"journal_article","author":[{"first_name":"Michael S.","full_name":"Inkpen, Michael S.","last_name":"Inkpen"},{"first_name":"Zhen–Fei","full_name":"Liu, Zhen–Fei","last_name":"Liu"},{"last_name":"Li","first_name":"Haixing","full_name":"Li, Haixing"},{"last_name":"Campos","full_name":"Campos, Luis M.","first_name":"Luis M."},{"last_name":"Neaton","full_name":"Neaton, Jeffrey B.","first_name":"Jeffrey B."},{"first_name":"Latha","full_name":"Venkataraman, Latha","orcid":"0000-0002-6957-6089","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","last_name":"Venkataraman"}],"citation":{"short":"M.S.

Such approaches for expanding the range of chemical entities that can be produced by the ribosome may accelerate the discovery of molecules that can perform functions for which poorly folded, short peptidic sequences are ill suited. Here, we show that the ribosome tolerates some artificial helical aromatic oligomers, so-called foldamers. Using a flexible tRNA-acylation ribozyme—flexizyme—foldamers were attached to tRNA, and the resulting acylated tRNAs were delivered to the ribosome to initiate the synthesis of non-cyclic and cyclic foldamer–peptide hybrid molecules. Passing through the ribosome exit tunnel requires the foldamers to unfold. Yet foldamers encode sufficient folding information to influence the peptide structure once translation is completed. We also show that in cyclic hybrids, the foldamer portion can fold into a helix and force the peptide segment to adopt a constrained and stretched conformation.","lang":"eng"}],"_id":"21097","oa_version":"None","external_id":{"pmid":["29556052"]}},{"publisher":"Springer Nature","language":[{"iso":"eng"}],"page":"523-531","publication_identifier":{"issn":["1755-4330"],"eissn":["1755-4349"]},"volume":10,"acknowledgement":"We thank B.

Here, we generalize the strategy used to probe free-energy landscapes in protein folding to determine the activation energies and entropies that characterize each of the molecular steps in the aggregation of the amyloid-β peptide (Aβ42), which is associated with Alzheimer’s disease. Our results reveal that interactions between monomeric Aβ42 and amyloid fibrils during fibril-dependent secondary nucleation fundamentally reverse the thermodynamic signature of this process relative to primary nucleation, even though both processes generate aggregates from soluble peptides. By mapping the energetic and entropic contributions along the reaction trajectories, we show that the catalytic efficiency of Aβ42 fibril surfaces results from the enthalpic stabilization of adsorbing peptides in conformations amenable to nucleation, resulting in a dramatic lowering of the activation energy for nucleation.","lang":"eng"}],"external_id":{"pmid":["29581486"]}},{"fulldoi":"https://doi.org/10.1038/nchem.2303","doi":"10.1038/nchem.2303","scopus_import":"1","article_processing_charge":"No","year":"2015","date_created":"2023-08-01T09:44:33Z","publication_status":"published","article_type":"original","intvolume":"         7","quality_controlled":"1","date_updated":"2024-10-14T12:17:47Z","publication":"Nature Chemistry","pmid":1,"date_published":"2015-07-20T00:00:00Z","abstract":[{"lang":"eng","text":"The ability to guide the assembly of nanosized objects reversibly with external stimuli, in particular light, is of fundamental importance, and it contributes to the development of applications as diverse as nanofabrication and controlled drug delivery.

Here we describe a conceptually new methodology to assemble NPs reversibly using light that does not require the particles to be functionalized with light-responsive ligands. Our strategy is based on the use of a photoswitchable medium that responds to light in such a way that it modulates the interparticle interactions.

Over decades chemists have developed a nuanced understanding of stereoelectronics to establish how the electronic properties of molecules relate to their conformation; the recent advent of single-molecule break-junction techniques provides the means to alter this conformation with a level of control previously unimagined. Here we unite these ideas by demonstrating the first single-molecule switch that operates through a stereoelectronic effect. We demonstrate this behaviour in permethyloligosilanes with methylthiomethyl electrode linkers. The strong σ conjugation in the oligosilane backbone couples the stereoelectronic properties of the sulfur–methylene σ bonds that terminate the molecule. Theoretical calculations support the existence of three distinct dihedral conformations that differ drastically in their electronic character. We can shift between these three species by simply lengthening or compressing the molecular junction, and, in doing so, we can switch conductance digitally between two states.","lang":"eng"}],"_id":"17975","oa_version":"None","external_id":{"pmid":["25698330"]},"extern":"1","OA_type":"closed access","title":"Stereoelectronic switching in single-molecule junctions","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"16","month":"02","status":"public","volume":7,"publication_identifier":{"issn":["1755-4330"],"eissn":["1755-4349"]},"publisher":"Springer Nature","page":"215-220","language":[{"iso":"eng"}],"author":[{"last_name":"Su","full_name":"Su, Timothy A.","first_name":"Timothy A."},{"last_name":"Li","full_name":"Li, Haixing","first_name":"Haixing"},{"last_name":"Steigerwald","full_name":"Steigerwald, Michael L.","first_name":"Michael L."},{"first_name":"Latha","orcid":"0000-0002-6957-6089","full_name":"Venkataraman, Latha","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","last_name":"Venkataraman"},{"last_name":"Nuckolls","first_name":"Colin","full_name":"Nuckolls, Colin"}],"citation":{"chicago":"Su, Timothy A., Haixing Li, Michael L.

Here we demonstrate that charge carriers in single-molecule junctions can be tuned within a family of molecules that contain electron-deficient thiophene-1,1-dioxide (TDO) building blocks. Oligomers of TDO were designed to increase electron affinity and maintain delocalized frontier orbitals while significantly decreasing the transport gap. Through thermopower measurements we show that the dominant charge carriers change from holes to electrons as the number of TDO units is increased. This results in a unique system in which the charge carrier depends on the backbone length, and provides a new means to tune p- and n-type transport in organic materials."}],"oa_version":"None","external_id":{"pmid":["25698329"]}},{"type":"journal_article","author":[{"last_name":"Klajn","first_name":"Rafal","id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b","full_name":"Klajn, Rafal"},{"last_name":"Olson","first_name":"Mark A.","full_name":"Olson, Mark A."},{"full_name":"Wesson, Paul J.","first_name":"Paul J.","last_name":"Wesson"},{"first_name":"Lei","full_name":"Fang, Lei","last_name":"Fang"},{"full_name":"Coskun, Ali","first_name":"Ali","last_name":"Coskun"},{"last_name":"Trabolsi","full_name":"Trabolsi, Ali","first_name":"Ali"},{"first_name":"Siowling","full_name":"Soh, Siowling","last_name":"Soh"},{"full_name":"Stoddart, J.

In such heterogeneous systems, the components interact with one another by means of programmable, noncovalent bonding interactions. Herein, we describe polymers that capture and release functionalized nanoparticles selectively during redox-controlled aggregation and disaggregation, respectively. The interactions between the polymer and the NPs are mediated by the reversible formation of polypseudorotaxanes, and give rise to architectures ranging from short chains composed of few nanoparticles to extended networks of nanoparticles crosslinked by the polymer. In the latter case, the polymer/nanoparticle aggregates precipitate from solution such that the polymer acts as a selective ‘sponge’ for the capture/release of the nanoparticles of different types.","lang":"eng"}],"_id":"13415","oa_version":"None","date_published":"2009-12-01T00:00:00Z","publication":"Nature Chemistry","pmid":1,"date_updated":"2023-08-08T08:55:36Z","quality_controlled":"1","intvolume":"         1","publication_status":"published","article_type":"original","date_created":"2023-08-01T09:50:23Z","year":"2009","scopus_import":"1","article_processing_charge":"No","fulldoi":"https://doi.org/10.1038/nchem.432","doi":"10.1038/nchem.432"}]
