A series of polymers based on 8,8′‐biindeno[2,1‐b]thiophenylidene for use in photovoltaic devices and field‐effect transistors are reported. These structurally twisted olefins are effective building blocks for preparation of low bandgap polymers with optical bandgaps of 1.2–1.5 eV. Device performance, such as Voc and Jsc, in solar cell devices could be successfully modulated by incorporation of a variety
据报道,一系列基于8,8'-双茚并[2,1-b]硫代亚苯基的聚合物可用于光伏器件和场效应晶体管。这些结构扭曲的烯烃是制备带隙为1.2–1.5 eV的低带隙聚合物的有效构建基。通过掺入多种共聚单体,可以成功地调节太阳能电池器件中的器件性能,例如V oc和J sc。还研究了使用Au电极的场效应晶体管的双极性特性,其中P t BTPDPP表现出平衡的电荷传输特性,空穴和电子迁移率分别为0.09和0.12 cm 2 ·V -1 ·s -1, 分别。©2015 Wiley Periodicals,Inc. J. Polym。科学,A部分:Polym。化学 2016,54,889-899
