Abstract

Novel copolymers consisting of the alternating push-pull comonomers fluorene and thieno[3,4-b]pyrazine/quinoxaline were synthesized by a palladium-catalyzed Suzuki cross-coupling reaction in 60-80% yields. The structure of the deeply colored copolymers was confirmed with ¹H and ¹³C NMR. All the new materials were characterized with spectroscopic and electrochemical methods. Bulk heterojunction organic solar cells based on some of the novel polymers in combination with the well-known fullerene acceptor [6,6]-phenyl C₆₁-butyric acid methyl ester were fabricated, and their photovoltaic parameters were measured.
