A mechanistic electrochemical study ofbis-(azaferrocene-15-crown-5-ether) at a glassy carbon electrode

Abstract

The work described in this paper concerns the electrochemical behaviour ofbis-(azaferrocene-15-crown-5-ether) at a glassy carbon electrode using CV, CA, and CP techniques. On sweeping to positive direction, a one electron quasi-reversible oxidation wave coupled with a following chemical reaction is observed. Values of the chemical rate constantkc, the rate constant of heterogeneous electron transferk0, the half-wave potentialE1/2, the transfer coefficient α, and the diffusion coefficientD of the depolarizer species are determined and discussed.
