and P(DTBDAT‐TCNT) were similar. The structure properties of thin films of these materials were characterized using grazing‐incidence wide‐angle X‐ray scattering and tapping‐mode atomic force microscopy, and charge carrier mobilities were characterized using the space‐charge limited current method. OSCs were formed using [6,6]‐phenyl‐C71‐butyric acid methyl ester (PC71BM) as the electron acceptor and

DAT-TCNT)的溶液吸收最大值红移了5-15 nm 。P(BDT-TCNT)和P(DTB
DAT-TCNT)的光学带隙和最高占据分子轨道(HOMO)能级相似。利用掠入射宽角X射线散射和振型原子力显微镜表征了这些材料的薄膜的结构特性,并使用空间电荷限制电流方法表征了载流子迁移率。OSC是使用[6,6]-苯基-C 71-
