Dithienonaphthalene and dithienochrysene derivatives that bear diarylaminophenyl groups were prepared in two steps from commercially available compounds via a Sonogashira coupling, followed by a simple sulfur-mediated thienannulation. Owing to their relatively narrow HOMO–LUMO gaps, the thus obtained compounds showed bathochromically shifted UV-Vis absorption and fluorescence spectra with higher quantum yields compared to the molecules without the diarylaminophenyl groups. Moreover, the suitable energy levels of their HOMOs and reversible redox properties permit applications for these compounds in hole-transporting layers in perovskite solar cells.

基于硫介导的噻吩并噻吩稠合的芳烃的空穴传输材料†

带有二芳基氨基苯基的二噻吩萘和二噻吩并二烯衍生物是通过Sonogashira偶联从市售化合物分两步制备的，然后进行简单的硫介导的噻吩环化。与没有二芳基氨基苯基的分子相比，由于它们的HOMO-LUMO间隙相对较窄，因此得到的化合物显示出红移的紫外可见吸收和荧光光谱，具有更高的量子产率。此外，它们的HOMO的合适能级和可逆的氧化还原性质允许将这些化合物应用在钙钛矿太阳能电池的空穴传输层中。
