The creation of highly fluorescent materials should be an urgent and significant subject. For this purpose, we designed the novel pi-conjugated compounds having indro[3,2,1-jk]carbazole (IC) and 9,9'-diphenyl-4,4',5,5'-biscarbazole (DBC) as a framework, synthesized them, and elucidated their photophysical properties and functions.We investigated the photophysical properties of synthesized compounds. As a result, the bathochromic shift of the fluorescence maximum and the increase of quantum yield in three IC derivatives were observed by comparison with those of IC in solution state. In solid state, although the further bathochromic shift of the fluorescence maximum of all IC derivatives were observed, the only one IC derivative showed the increase of quantum yield. On the other hand, neither of the bathochromic shift of the fluorescence maximum and the increase of quantum yield in two DBC derivatives were observed by comparison with those of DBC in solution and solid state.

高荧光材料的产生应该是一个紧迫而重要的课题。 为此，我们设计并合成了以吲哚[3，2，1-jk]咔唑（IC）和9，9 ′-二苯基-4，4 ′，5，5 ′-双咔唑（DBC）为骨架的π共轭化合物，并对其物理性质和功能进行了研究。 结果表明，三种IC衍生物的最大荧光峰均发生红移，量子产率均比溶液中的IC有所提高。 在固态下，尽管所有IC衍生物的荧光最大值均进一步红移，但只有一个IC衍生物的量子产率有所增加。 另一方面，通过与溶液和固体状态的DBC相比，没有观察到两种DBC衍生物的荧光最大值的红移和量子产率的增加。
