  摘要：

  成功设计、合成了角形n型半导体2-(12 H-二苯并芴-12-亚基)丙二腈二亚胺2a和2b，并通过光吸收和荧光、循环伏安法、X射线晶体结构分析、XRD进行了充分表征和 OFET 器件性能。2a和2b的不同烷基链长度导致相对于底物的不同分子取向。因此，2a的电子迁移率为 0.01 cm 2 V –1 s –1，而2b导致器件性能差，电子迁移率低得多，为 5 × 10 –4cm 2 V –1 s –1。

  A nickel-catalyzed molybdenum-promoted carbonylative coupling reaction for the synthesis of benzophenones from aryl iodides has been developed. Various substituted diaryl ketones were synthesized in moderate to excellent yields under CO-gas-free conditions. A synergetic effect of both nickel and molybdenum has been observed, which is also responsible for the success of this transformation.
