合成了一系列3，6-二氨基-9-萘基咔唑衍生物，并对其进行了实验和计算表征。由于萘基的最低未占分子轨道具有比苯基低的能量，因此在激发态下发生从咔唑到萘基的电荷转移，从而引起荧光量子产率的溶剂化荧光和溶剂依赖性。在萘环上有两个咔唑取代基的分子在激发态具有470 nm的吸收和高的还原能力。该分子在可见光照射下可成功地光敏化卤代芳烃的加氢脱卤反应。
A series of 3,6-diamino-9-naphthylcarbazole derivatives were synthesized and characterized experimentally and computationally. As the lowest unoccupied molecular orbital of the naphthyl group has lower energy than that of the phenyl group, a charge transfer from carbazole to naphthyl in the excited states occurred causing solvatofluorochromism and solvent-dependency in fluorescence quantum yields. A molecule having two carbazole substituents sandwiching the central naphthyl ring had absorption reaching 470 nm and a high reducing capability in the excited state. This molecule could successfully photosensitize the hydrodehalogenation of haloarenes under visible light irradiation.
