Electrochemical investigation of a podand type diimine polyether

A podand type diimine polyether, 1,8-di[N-2-oxyphenyl-salicylidene]-3,6-dioxaoctane (DSO), was prepared and its electrochemical behaviour reported. The reduction of the -C=N- bonds in this compound was studied in a 1:5 (v/v) ethyl alcohol-water mixture using sampled current polarography, cyclic voltammetry, chronoamperometry and chronocoulometry. Adsorption characteristics of the compound on the mercury electrode were examined and the amount of adsorption of the molecule was calculated. Considering the adsorption of the compound on the electrode surface, heterogeneous rate constants of the electrode transfer reaction were defermined by cylic voltammetric measurements.
