Donor-acceptor-Type Polymers Based on Dithieno[2,3-b;7,6-b]carbazole Unit for Photovoltaic Applications

[摘要]：Dithieno[2,3-b;7,6-b]carbazole (TCZT), a type of heteropentacene with nitrogen and sulfur atoms, was synthesized with a focus on the unique reactivity of carbazole via double intramolecular Friedel-Crafts acylation. A donor-acceptor-type polymer (PTCZTBT) was also synthesized, and Its physicochemical properties are reported.
