AbstractWe will show the synthesis of new donor-acceptor copolymers based on 2,7-carbazole or 2,7-dibenzosilole and acenaphtho[1,2-b]thieno[3,4-e]pyrazine. After the synthesis of these new copolymers, we have characterized the materials by UV-vis, DSC, and XRD to determine the degree of organization. Afterward, we have fabricated and investigated field-effect transistors and photovoltaic cells from these polymers. The optimization of the thin film by thermal treatment have led to a field-effect mobility of 0.04 cm2/(V.s) and power conversion efficiency of 0.44%.
