Polythiophenes are a class of conjugated polymers having good environmental stability which, due to their ease of synthetic modification, are thought to be one of the most versatile of this class of polymers. A class of modified polythiophene materials utilizing dithieno[3,2-b:2',3'-d]pyrroles (DTPs) have been shown to exhibit improved electronic and optical properties in comparison to poly(3-alkylthiophene)s. The addition of ethylene units to the polymer backbone has been shown to be a successful approach to the lowering of the polymer band gap, and thus efforts to combine this approach with our previous application of the fused-ring DTPs is a current goal. The synthesis and characterization of DTP-based arylenevinylene polymers will be presented.
