Voltammetric behavior of the C60-γ-cyclodextrin inclusion complex (1:2) on hmde in an aqueous solution

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.
