Novel heteroarene-fused dispiro compounds, dispiro[9H-fluorene-9,5'(6'H)-diindeno[1,2-b:2',1'-d]furan-6',9''-[9H]fluorene] (dsp-DIF), dispiro[9H-fluorene-9,5'(6'H)-diindeno[1,2-b:2',1'-d]thiophene-6',9''-[9H]fluorene] (dsp-DIT), and 11-phenyldispiro[9H-fluorene-9,5'(6'H)-diindeno[1,2-b:2',1'-d]pyrrole-6',9''-[9H]fluorene] (dsp-DIP-Ph) have been synthesized. Their structures were unambiguously determined by X-ray crystallography. These three dispiro compounds showed blue fluorescence with moderate quantum yields.
新型杂芳环稠合双螺环化合物，螺[9H-芴-9,5'-(6'H)-二茚并[1,2-b:2',1'-d]呋喃-6',9''-[9H]芴]（dsp-DIF）、螺[9H-芴-9,5'-(6'H)-二茚并[1,2-b:2',1'-d]噻吩-6',9''-[9H]芴]（dsp-DIT）和 11-苯基螺[9H-芴-9,5'-(6'H)-二茚并[1,2-b:2',1'-d]吡咯-6',9''-[9H]芴]（dsp-DIP-Ph）已被合成。它们的结构通过 X 射线晶体学得到了明确的确定。这三种双螺环化合物表现出中等量子产率的蓝色荧光。
