Synthesis and characterization of β,β′-dimethylated dithieno[3,2-b:2′,3′-d]pyrroles and their corresponding regioregular conducting electropolymers

beta,beta'-Dimethyl-substituted dithieno[3,2-b:2',3'-d]pyrroles (Me-DTP) 2-7 represent novel electron-rich building blocks, which were converted to corresponding conducting polymers p(Me-DTP) and to func-tional dyes for organic electronic applications. Supported by quantum chemical calculations, structural and optoelectronic properties of the three types of pi-conjugated materials were investigated and led to valuable structure-property relationships.
