Development of Structure Controlled Network Polymers Utilizing Conjugated Polymers

Abstract

This article deals with recent research on construction and control of network of conjugated polymers, mainly poly(acetylene)s and poly (phenyleneethynylene)s utilizing intra/intermolecular interaction and/or crosslinking. Bi- and multi-functional substituted acetylene monomers give poly(acetylene)-based network polymers exhibiting stimuli-response, chiral recognition and catalysis. Poly(acetylene)s substituted with benzoxazine moieties are thermally highly stable due to the rigid poly(acetylene) backbone. Poly(phenyleneethynylene)s give stable network polymers by crosslinking at the side chains. The higher order structures of platinum-containing poly(phenyleneethynylene)s are controllable by network formation with bisphosphine ligands.
