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
新颖的杂芳烃稠合的螺化合物,螺[9 ħ芴-9,5'(6' ħ)-diindeno [1,2 b:2',1' - d ]呋喃6',9'' - [ 9 ħ ]芴](DSP-DIF),二螺[9 ħ芴-9,5'(6' ħ)-diindeno [1,2 b:2',1' - d ]噻吩6',9 '' - [9 ħ ]芴](DSP-DIT),和11-phenyldispiro [9 ħ芴-9,5'(6' ħ)-diindeno [1,2 b:2',1,1'- d ]吡咯-6',9''-[9 H ]芴](dsp-DIP-Ph)已合成。通过X射线晶体学明确地确定了它们的结构。这三种双螺化合物具有适度的量子产率的蓝色荧光。
