A series of novel thiophene-flanked benzodipyrrolidone (BPT)-based alternating copolymers are synthesised, their optical and electrical properties evaluated. The BPT unit promotes a conjugated, planar polymer backbone, with a low bandgap, primarily due to low lying LUMO energy levels. Copolymerisation with thiophene exhibits well balanced ambipolar organic field-effect transistor performance, with electron and hole mobilities 0.1 and 0.2 cm2 V−1 s−1, respectively.
合成了一系列新型的以噻吩为夹层的苯并二吡咯烷酮(BPT)为基础的交替共聚物,并对其光学和电学性能进行了评估。BPT单元促进了共轭平面聚合物骨架的形成,其低带隙主要归因于较低的LUMO能级。与噻吩共聚合表现出良好的平衡的双极有机场效应晶体管性能,电子和孔的迁移率分别为0.1和0.2 cm² V⁻¹ s⁻¹。
