Tam, Eugenia S. published the artcileSingle-Molecule Conductance of Pyridine-Terminated Dithienylethene Switch Molecules, Recommanded Product: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is ACS Nano (2011), 5(6), 5115-5123, database is CAplus and MEDLINE.

The authors have studied the conductance of individual optically switchable dithienylethene mols. in both their conducting closed configuration and nonconducting open configuration, using the technique of repeatedly formed break-junctions. The authors employed pyridine groups to link the mols. to gold electrodes to achieve relatively well-defined mol. contacts and stable conductance. For the closed form of each mol., the authors observed a peak in the conductance histogram constructed without any data selection, allowing the authors to determine the conductance of the fully stretched mols. For two different dithienylethene derivatives, these closed-configuration conductances were (3.3 ± 0.5) × 10-5G0 and (1.5 ± 0.5) × 10-6G0, where G0 is the conductance quantum. For the open configuration of the mols., the existence of elec. conduction via the mol. was evident in traces of conductance vs. junction displacement, but the conductance of the fully stretched mols. was less than the noise floor of the authors’ measurement. The authors can set a lower limit of 30 for the on/off ratio for the simplest dithienylethene derivative the authors have studied. D. functional theory calculations predict an on/off ratio consistent with this result.
