| Conjugated polymers utilizing fused-ring repeat units typically exhibit improved optical and electronic properties due to their lowered bad gap. One such system, poly(dithieno[3,2-b:2’,3’-d]pyrrole)s (DTPs) has not been fully investigated because the monomeric precursors require extensive synthesis with overall low yields. A newly established, simple and more effective route to the monomers has provided easy access to a variety of N-functionalized DTPs. Complete characterization utilizing electrochemical and photophysical analyses has been performed to compare side chain effects on the polymer properties. The polymers have also been found to exhibit properties desirable for applications such as light emitting diodes. Monomer synthesis, polymerization studies, and the photophysical and electrochemical properties will be discussed. |
