both compounds exhibiting p‐type semiconducting behavior. Thin films or microcrystals of THA1 possess relatively high hole mobility. Moreover, the mobilities of the microcrystal of THA1 along three directions are in the same order, thus the hole‐carrier transporting within the hexagonal‐plane of microcrystal of THA1 exhibits lessanisotropicbehavior. In comparison, both thin films and microrods of
(BT) or dibromodithienyldiketopyrrolopyrrole (DPP), via Stille polymerization. By varying the feed ratio of the monomers, a new series of random copolymers PTPTPTBT11, PTPTPTBT12, PTPTPTDPP11, PTPTPTDPP12, and PTPTPTDPP13 with tunable optical and electronic properties were prepared. The PTPTPTDPP12/PC71BM (1:4, w/w) based device exhibited the highest short circuit current (Jsc) of 10.78 mA/cm2 with a
我们已经开发出一种梯型多稠合的噻吩基-亚苯基-噻吩基-亚苯基-噻吩基(TPTPT)单元,其中每个噻吩环通过碳桥与相邻的苯环共价固定,从而形成四个嵌在非无环结构中的环戊二烯环。通过Stille聚合,将这种刚性且共面的TPTPT结构单元与缺电子受体,二溴苯并噻二唑(BT)或二溴二噻吩基二酮基吡咯并吡咯(DPP)进行共聚。通过改变单体的进料比,制备了具有可调的光学和电子性质的新系列的无规共聚物PTPTPTBT11,PTPTPTBT12,PTPTPTDPP11,PTPTPTDPP12和PTTPTPDPP13。基于PTPTPTDPP12 / PC 71 BM(1:4,w / w)的设备表现出最高的短路电流(J sc)为10.78 mA / cm 2,具有很高的功率吸收效率和PTPTPTDPP12的最高空穴迁移率,因此功率转换效率(PCE)为4.3%。基于PTPTPTDPP13,PTPTPTDPP11
