Single Molecule Conductance of Electroactive Helquats: Solvent Effect
Original language description
A series of helquat molecules with increasing number of rings n was studied by electrochemical and break junction methods to provide redox characteristics and single molecule conductance properties. Even though selected species do not contain anchoring groups the molecular junction conductance was observed experimentally and depends strongly on the solvent used. Single molecule conductance G is almost two orders of magnitude higher in water environment compared to mesitylene, whereas the distribution of G values is narrow in water and wide in mesitylene solvent. In the non-polar environment, G increases with increasing n, contrary to generally accepted notion of decreasing tunneling current with increasing molecular length. This behavior is, however, consistent with electrochemical properties, which showed that longer helquats are reduced more easily than the shorter ones. Furthermore, theoretical computations provided most probable molecular junction configurations of helquats in water solvent with excellent agreement between theoretical and experimental G values.
