제목 Synthesis and Characterization of New Alternating Copolymer Containing Dialkoxy Naphthalene and Carbonylated Thieno[3,4-b]thiophene for OTFT and OPV
초록 In this study, we designed and developed new donor-acceptor copolymer for OTFT and OPV.
PONTET composed of dialkoxy napthalene as donor and a carbonylated thieno[3,4-b]thiophene group as an acceptor was obtained by Suzuki coupling polymerization. PONTET showed broad absorption with a maximum at 534 nm in solution and 618 nm in a thin film, respectively. The hole mobility of PONTET was 1.5×10-3 cm2/Vs and the Ion/Ioff ratio was 7.7×104. The maximum power conversion efficiency of a PONTET:PC70BM (1:4)-based solar cell reached 1.3% with an open circuit voltage (Voc) of 0.56 V, a short circuit current density (Jsc) of 5.6 mA/cm2, and a fill factor (FF) of 41.3%.
