Abstract:The electron self-exchange rates (kex) of viologen and its derivatives are estimated by using microelectrode voltammetry in poly(ethylene glycol) films. The dependences of supporting electrolyte concentration and sizes of viologen and its derivatives on kex and diffusion coefficients (D) are discussed. Results show that kex increases with the decrease of supporting electrolyte concentration and sizes of reactants.
