Light emission of [10]cyclophenacene through energy transfer from neighboring carbazolylphenyl dendrons.
A dendritic deca(carbazolylphenyl)[60]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.
