Synthesis of dye linked conducting block copolymers, dye linked conducting homopolymers and preliminary application to photovoltaics

A synthetic approach to the synthesis of a large super molecule composed of two chemically different conducting polymer blocks with, respectively, high and low lying electronic energy levels linked through a porphyrin dye molecule is presented. The synthetic strategies to these molecular architectures are discussed.

Finally the molecular systems are applied to make photovoltaic devices and the rather low efficiency is discussed in terms of the synthetic approach. (C) 2004 Elsevier B.V. All rights reserved.
