indoles and elemental sulfur has been reported. The present approach produces a range of structurally valuable fused thienoindoles in 51–78% yield under transition-metal-free conditions, which may have potential applications in pharmaceutical industry and organic functional materials. In this work, the double C−S bonds formation is achieved via base promoted direct sulfuration of C−H bonds with elemental

The nitrogenization of phenyl rings on DIM derivatives not only enhances molecular coplanarity but also stabilizes molecular LUMO levels, favoring charge transfer and improving air stability. Therefore, n-typeorganic field-effect transistors (OFETs) that are based on DIM-N2C8 with nitrogen atoms on both sides of the phenyl rings exhibit a moderate electron mobility of 0.059 cm2 V–1 s–1 under ambient
DIM衍生物上苯环的氮化不仅增强了分子的共面性,而且还稳定了分子LUMO的水平,有利于电荷转移并改善了空气稳定性。因此,基于DIM-N2C8且苯环两侧均带有氮原子的n型有机场效应晶体管(OFET)在环境条件下具有0.059 cm 2 V –1 s –1的中等电子迁移率。
