With the help of man-made molecular photoswitches, we now have the potential to outperform natural systems in many ways, with the ultimate goal of fabricating multifunctional materials that operate at different light wavelengths. An important challenge in developing light-controlled artificial molecular machines lies in attaining a detailed understanding of the photoisomerization-coupled conformational changes that occur in macromolecules and molecular assemblies. In this issue of ACS Nano, Bléger, Rabe, and co-workers use force microscopy to provide interesting insights into the behavior of individual photoresponsive molecules and to identify contraction, extension, and crawling events accompanying light-induced isomerization.","lang":"eng"}],"publisher":"American Chemical Society","language":[{"iso":"eng"}],"month":"12","_id":"13399","citation":{"apa":"Kundu, P.

Here, we demonstrate that the energy profile for metallic single-atom contacts and single-molecule junctions can be mapped by fitting ambient atomic force microscope measurements carried out in the near-equilibrium regime to a physical, but simple, functional form. We extract bond energies for junctions formed through metallic bonds as well as metal–molecule link bonds from atomic force microscope data and find that our results are in excellent quantitative agreement with density functional theory based calculations for exemplary junction structures. Furthermore, measurements from a large number of junctions can be collapsed to a single, universal force–extension curve, thus revealing a surprising degree of similarity in the overall shape of the potential surface that governs these chemical bonds. Compared to previous studies under ambient conditions where analysis was confined to trends in rupture force, our approach significantly expands the quantitative information extracted from these measurements, particularly allowing analysis of the trends in bond energy directly.","lang":"eng"}],"article_type":"original","volume":8,"date_created":"2024-09-09T11:07:34Z","oa_version":"None","pmid":1,"OA_type":"closed access","intvolume":"         8","external_id":{"pmid":["24945851"]},"scopus_import":"1"},{"extern":"1","issue":"4","doi":"10.1021/nn4007187","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"23","publication_status":"published","status":"public","volume":7,"date_created":"2024-09-09T11:34:27Z","article_type":"original","abstract":[{"lang":"eng","text":"We measure simultaneously force and conductance of Ag metal point-contacts under ambient conditions at room temperature.

We also find two additional conductance features at ∼0.4 G0 and ∼1.3 G0, which have been previously ascribed to contacts with oxygen contaminations. Here, using a conductance cross-correlation technique, we distinguish three different atomic-scale structural motifs and analyze their rupture forces and stiffness. Our results allow us to assign the ∼0.4 G0 conductance feature to an Ag–O–Ag contact and the ∼1.3 G0 feature to an Ag–Ag single-atom contact with an oxygen atom in parallel.

In these measurements, conductance is measured as a function of electrode displacement yielding data that is analyzed by constructing conductance histograms to determine the most frequently observed conductance values in the nanoscale junctions. However much of the rich physics in these measurements is lost in this simple analysis technique. Conductance histograms cannot be used to study the statistical relation of distinct junction configurations, to distinguish structurally different configurations that have similar conductance values, or to obtain information on the relation between conductance and junction elongation. Here, we give a detailed introduction to a novel statistical analysis method based on the two-dimensional cross-correlation histogram (2DCH) analysis of conductance traces and show that this method provides new information about the relation of different junction configurations that occur during the formation and evolution of metal and single-molecule junctions. We first illustrate the different types of correlation effects by using simulated conductance traces. We then apply this analysis method to several different experimental examples. We show from break-junction measurements of different metal point-contacts that in aluminum, the first conductance histogram peak corresponds to two different junction structures. In tantalum, we identify the frequent absence of adhesive instability. We show that conductance plateaus shift in a correlated manner in iron and vanadium junctions. Finally, we highlight the applicability of the correlation analysis to single-molecule platinum–CO–platinum and gold–4,4′-bipyridine–gold junctions.","lang":"eng"}],"publication_status":"published","status":"public","doi":"10.1021/nn300440f","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"07","issue":"4","extern":"1","publication":"ACS Nano","article_processing_charge":"No","publication_identifier":{"issn":["1936-0851"],"eissn":["1936-086X"]},"quality_controlled":"1","title":"Correlation analysis of atomic and single-molecule junction conductance","author":[{"last_name":"Makk","first_name":"Péter","full_name":"Makk, Péter"},{"last_name":"Tomaszewski","first_name":"Damian","full_name":"Tomaszewski, Damian"},{"first_name":"Jan","last_name":"Martinek","full_name":"Martinek, Jan"},{"full_name":"Balogh, Zoltán","last_name":"Balogh","first_name":"Zoltán"},{"full_name":"Csonka, Szabolcs","last_name":"Csonka","first_name":"Szabolcs"},{"full_name":"Wawrzyniak, Maciej","first_name":"Maciej","last_name":"Wawrzyniak"},{"full_name":"Frei, Michael","last_name":"Frei","first_name":"Michael"},{"full_name":"Venkataraman, Latha","last_name":"Venkataraman","first_name":"Latha","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","orcid":"0000-0002-6957-6089"},{"first_name":"András","last_name":"Halbritter","full_name":"Halbritter, András"}],"date_published":"2012-03-07T00:00:00Z","type":"journal_article","publisher":"American Chemical Society","language":[{"iso":"eng"}],"month":"03","_id":"18008","page":"3411-3423","date_updated":"2025-01-03T09:10:24Z","citation":{"ama":"Makk P, Tomaszewski D, Martinek J, et al.
