The electrochemical properties of four C60derivatives (compounds 1∼4) were investigated with cyclic voltammetry (CV), and compared with that of C60. The reduction potentials of compound 1∼3 shifted to more negative positions than C60, and their oxidation peaks appeared at the lower potentials. Significantly, the reduction potentials of compound 4 shifted to more positive positions than C60, which is advantageous to form charge-transfer complexes with more donors. So the reduction properties in different solvents andin situNIR absorption spectra of compound 4 were studied in more details. In addition, the AM1 molecular orbital calculation was performed on C60and compound 1∼4 for the explanation of the potential shifts. The reduction potentials of these compounds exhibited good linear relationships with the calculation LUMO or LUMO+1 energy levels.
