Synthesis and Photophysical Properties of C60-carbazole Adducts

Three C60-carbazole adducts have been synthesized by 1, 3-dipolar cycloaddition reaction. Intramolecular energy/electron transfer from carbazole to C60 was observed by steady-state absorption and fluorescence spectra. The fluorescence spectra of these adducts were similar to each other and dependent on the excitation wavelength and solvent.
