Electrochemically Controlled Conductance Switching in a Single Molecule: Quinone-Modified Oligo(phenylene vinylene)
Source abstract
Abstract
Reversible conductance switching in single quinone-oligo(phenylene vinylene) (Q-OPV) molecules was demonstrated using electrochemical STM. The switching was achieved by application of electrochemical potential to the substrate supporting the molecule. The ratio of conductances between the high- and low-conductivity states is over 40. The high-conductivity state is ascribed to strong electron delocalization of the fully conjugated hydroquinone-OPV structure, whereas the low-conductivity state is characterized by disruption of electron delocalization in the quinone-OPV structure.

26. A rough estimate, made from a comparison of the charge exchanged between the substrate and Q-OPVs in a single oxidation/reduction wave (Figure2A) and the number of spots seen in ESTM images (Figure2B), shows that each spot contains fewer than three Q-OPV molecules on average.
