Interest in conjugated polymers has been growing in recent years due to their unique  ability to adjust their optical and electronic properties at the molecular level, as well their potential ease of manufacture in electrical devices.  A main axis of research in our lab has been the development of a class of polythiophenes utilizing fused-ring dithieno[3,2-b:2',3'-d]pyrroles (DTPs).  Through work in our laboratory and others, DTP-based materials have been shown to give high carrier mobilities, enhanced fluorescence, and reduced or low band gaps.  Recent work has shown that the addition of an electron-withdrawing N-acyl group affords stabilization of the DTP HOMO and LUMO.  Using DTP as a template, we are currently investigating additional related analogues to explore the relation between structure and electronic properties.  The synthesis, characterization and material applications of DTPs and related analogues analogs will be presented.
