【Abstract】 Five C 60 indole adducts have been synthesized by 1,3 dipolar cycloaddition reaction. These compounds are characterized by 1?H NMR, FT IR, UV Vis. The fluorescence spectra show that they are similar to each other, with maximum *?0→0 emission at about 708?nm in CHCl 3 and fluorescence yields ca. 4 times, higher than that of pristine C 60 . The fluorescence lifetime (τ F) of 1a e is ca. 1.2?ns in toluene, which is very similar to that of C 60 .更多还原
