General description

DTS(FBTTh2)2 is a conductive polymer that can be used as a donor molecule. It has a narrow band gap and shows a maximum power conversion efficiency of 7.0%. Its photostability is more than that of P3HT.[1][2]

Application

DTS(FBTTh2)2 can be used as a conjugating polymer that forms a donor-acceptor system with acceptor molecules such as perylene diimide, PC71BM and other fullerenes for the fabrication of bulk-heterojunction based solar cells.[3][4][5]
