摘要
Photoinduced intramolecular events of newly synthesized bis(carbazole trimer)-C-60 adducts have been studied by laser flash photolysis techniques in polar and nonpolar solvents. For bis(tert-butyl-substituted carbazole trimer)-C-60 adduct, charge separation takes place via the excited singlet state of the C-60 moiety in polar solvents as revealed by the combination of the C-60-fluorescence quenching and transient absorptions of the radical ion pair. On the other hand, for bis(nonsubstituted carbazole trimer)-C-60 adduct, although charge separation takes place, the charge recombination is fast because of the lower electron-donor ability.
