| Abstract: | Electrochemical behavior of the water-soluble C60-γ-CD (1:2) inclusion complex has been studied on the hanging mercury drop electrode. A one-electron reversible adsorptive electro-reduction and three irreversible adsorptive electro-reductions were detected by cyclic voltammetry. The amount of C60-γ-CD adsorbed at saturation is 2.50 × 10?11 mol cm?2, the diffusion coefficient is 4.36 × 10?6cm2s?1 and the standard rate constant of the surface reaction ks are 0.745 s?1, 0.612 s?1 and 0.513s?1, respectively. |
