摘要

In this paper we show that bis(triarylamine) systems with conjugated bridges can be polymerised potentiodynamically. The resulting polymer films can be doped to a degree of ca. 75%per triarylamine unit. At 50%doping level the polymers show broad and intense intervalence charge-transfer bands. These IV-CT bands are quite similar to those in monomeric model compounds. Therefore, the polymers investigated can be regarded as polymeric mixed valence compounds.
