N2 - (Chemical Equation Presented) 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.
