A dendritic deca(carbazolylphenyl)fullerene bearing a cyclic benzenoid core was synthesized. The photophysical studies indicated that intramolecular energy transfer and electron transfer took place from the linked carbazolylphenyl moieties to the core−cyclic benzenoid moiety. The fluorescence quantum yield of the deca-adduct was determined to be 0.21 in toluene. Rich photophysical functions and their dendritic structures suggest that the photoactive decaadducts will serve as luminescent scaffolds in materials application.
