Abstract

Two novel conjugated polymers consisting of alternating thieno[3,4-b]thiophene and either carbazole (PCTT1) or carbazole with two thiophene spacers (PCTT2) were synthesized. PCTT1 (M_n44,000) showed a bandgap of 2.14 eV but a significantly deep highest occupied molecular orbital level of -5.52 eV. PCTT1-based photovoltaic devices showed promising power conversion efficiency of 2.53% under AM 1.5 G illumination at 100 mW/cm ².
