The Novel Electron Acceptor Based Copolymer for OTFT and OPV |
| 초록 |
A new copolymer composed of dialkoxy napthalene as donor and a carbonylated thieno [3,4-b]thiophene group as an acceptor, was obtained by Suzuki coupling polymerization. The number average molecular weight (Mn) of PONTET is 6.4 kg mol-1 with a polydispersity index of 1.20, determined by gel permeation chromatography using chloroform. A new copolymer showed broad absorption with a maximum at 534 nm in solution and 618 nm in a thin film, respectively. The hole mobility of a new copolymer 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 0.56V, a short circuit current density (Jsc) of 5.6 mA/cm2, and a fill factor (FF) of 41.3% |
