Abstract

Abstract : A new tetrafluoridequinoxaline electron accepting block- ff Qx from a quinoxaline core was designed. A new copolymer (PBDTT- ff Qx) was synthesized from tetrafluoridequinoxaline and benzodithiophene and a high PCE of 8.6% was obtained. Abstract : A new tetrafluoridequinoxaline electron accepting block from a quinoxaline core, which is substituted with a fluorine atom onto its backbone and side chains, was designed. A new copolymer (PBDTT- ff Qx) was synthesized from tetrafluoridequinoxaline and benzodithiophene. The copolymer was characterized in detail. The photovoltaic properties were well investigated. A high PCE of 8.6% based on the single junction device was obtained.
