Conveniently Processible Forms of Electrically Conductive Poly(Dibutoxyphenylene Vinylene)

Abstract

Abstract Highly versatile conductive polymers have been derived from a variety of readily prepared, conveniently processible precursor polymers to substituted poly(phenylene vinylenes). Key discoveries were made that facilitate processing of these precursor polymers. These include the ability to stabilize solutions of dialkoxyphenylene-vinylene precursor polymers against gel formation by the addition of weak amines, and the preparation of new non-ionic precursor polymers that can be processed from a wide range of solvents. In addition to structurally diverse precursor polymers, our recent discovery that strong protonic acids are generally applicable as dopants for conjugated polymers provides methodologies for directly processing these polymers in their highly conductive forms. Protonic acid doped conductive polymers can be obtained by thermal conversion of polyelectrolyte precursor polymers that contain conjugate bases of relatively non-volatile strong acids. Further, methods have been developed for the ...
