Abstract

Surface junction effects on the electron conduction of p -phenylene-bridged bis(terpyridine)iron oligomers terminated with a ferrocene moiety were quantitatively analyzed by employing three different surface-anchoring terpyridine ligands. The dependence of the electron-transfer rate constant for oxidation of the ferrocene moiety, k et, on the distance between the electrode surface and the ferrocene moiety, x , showed that the attenuation factor, βd, which indicates the degree of reduction of k et with x , was 0.018 in all cases. However, the absolute k et value depended strongly on both electronic and steric factors of the surface-anchoring ligand.
