| Abstract: | The electrochemical behavior of the water-soluble C60–γ-CD (1:1) inclusion complex has been studied on the hanging mercury drop electrode. A one-electron reversible adsorptive electroreduction and three irreversible adsorptive electroreductions were detected by cyclic voltammetry. The amount of C60–γ-CD adsorbed at saturation is 1.73 × 10?11 mol/cm2, the diffusion coefficient is 5.81 × 10?6 cm2/s, and the standard rate constant of the surface reaction ks are 0.888 s?1, 0.853 s?1 and 1.032 s?1, respectively. |
