Electropolymerization of triphenylamine–dithiafulvene hybrid extended pi-conjugated systems

Abstract

Extended hybrid conjugated systems based on a triphenylamine core with 1, 2 and 3 peripheral dithiafulvenyl units have been studied by cyclic voltammetry and UV-Vis absorption spectroscopy. The substitution pattern of the triphenylamine core determines two different electrochemical coupling mechanisms leading to two types of electrogenerated extended conjugated electroactive systems. The structure and properties of polymeric species are also presented.
