Department of Chemistry, South China Normal University, Guangzhou 510631, China; 2. Guangzhou Institute of Chemistry, Chinese Academy of Sciences, Guangzhou 510650, China) Abstract: Characterization of the charge transfer complexes of [ 60] fullerene have been studied by nanosecond laser photolysis. The electron transfer reaction from donors (TTF) to excited triplet state of [ 60] fullerene in benzonitrile have been confirmed by transient absorption spec troscopy in observing the decay of excited triplet state of [ 60] fullerene and rise of anion radical of [ 60] fullerene. ey words: charge transfer complexes; electron transfer reaction; nanosecond laser photolysis; [ 60] fullerene [ 60] Fullerene and their derivatives have become the current focus of research in photoconductiv [ 1,2] [ 3] [4~ 6] [7] ity , superconductivity , ferromagnetism and nonlinear optics . Especially, charge transfer complexes of [ 60] fullerene with donors have attracted considerable attention. Since th
