| Research Abstract |
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.
