✦ Synopsis

Electrochemical behavior of the water-soluble C,,-y-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 &,-y-CD adsorbed at saturation is 2.50 x lo-" molcm-', the diffusion coefficient is 4.36 x 10-6cm2 SK' and the standard rate constant of the surface reaction k, are 0.745s-', 0.612~~' and 0.513 SK', respectively.
