摘要

Novel indeno-spirobifluorene and dispirobifluorene derivatives were synthesized and characterized. Their two positional isomers were unambiguously determined by X-ray crystallography. Preliminary investigations indicated that these indeno-spirobifluorene and dispirobifluorenes showed blue fluorescence with good quantum yields (Φ> 60%) and excellent thermal stabilities.
