  • Title: Electrochemically controlled conductance switching in a single molecule: quinone-modified oligo(phenylene vinylene).

    Journal: ACS Nano; 2008 Jun; 2(6):1289-95. PubMed ID: 19206347.
    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.
