- We report on single molecule electron transport measurements of two oligophenylenevinylene (OPV3) derivatives placed in a nanogap between gold (Au) or lead (Pb) electrodes in a field effect transistor device. Both derivatives contain thiol end groups that allow chemical binding to the electrodes. One derivative has additional methylene groups separating the thiols from the delocalized pi-electron system. The insertion of methylene groups changes the open state conductance by 3-4 orders of magnitude and changes the transport mechanism from a coherent regime with finite zero-bias conductance to sequential tunneling and Coulomb blockade behavior.

Konferensbidrag (refereegranskat)abstract
- We have studied low temperature electron transport in three terminal single molecule transistors. Devices with OPV revealed a relation between transistor characteristics and position of molecular redox potentials strongly influenced by proximity to the metal. Fullerene based devices demonstrate negative differential resistance and indicate strong coupling of fullerene to gold.
