Two donor-acceptor (D-A) copolymer PDVTs based on diketopyrrolopyrole and (E)-2-(2-(thiophen-2-yl)vinyl)thiophene (TVT) units are synthesized for solution-processed field-effect transistors (FETs). The highly π-extended TVT units strengthen the coplanarity of the polymer backbone. FETs based on PDVTs show high mobilities above 2.0 cm(2) V(-1) s(-1) with a current on/off ratio of 10(5)-10(7) , high shelf storage, and operation stability.
两种基于二酮吡咯并吡咯(DPP)和(E)-2-(2-(噻吩-2-基)乙烯基)噻吩(TVT)单元的给体-受体(D-A)共聚物 PDVT 被合成出来，用于溶液处理场效应晶体管(FET)。高度扩展的 TVT 单元增强了聚合物主链的共面性。基于 PDVT 的 FET 表现出高于 2.0 cm(2) V(-1) s(-1)的高迁移率，电流开关比为 10(5)-10(7)，具有高货架存储和操作稳定性。
