Novel dispirobifluorenes and indeno-spirobifluorenes: syntheses and properties
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 (Phi>60%) and excellent thermal stabilities.
