Electrochemical studies of 1-ferrocenylmethyl-3-methyl-imidazolium iodide and 1-(ferrocenylmethyl)-3-mesityl-imidazolium iodide: redox potential and substituent effects

Abstract

The electrochemical behavior of 1-ferrocenylmethyl-3-(methyl)-imidazolium iodide (or mesityl) imidazolium was studied by cyclic voltammetry at glassy carbon electrode in midiums organic to determine the influences of electronic imidazolium group on the ferrocene. The experimental results indicated that the redox reaction was reversible. Mass transport towards the electrode is a simple diffusion process and the diffusion coefficient (D) for redox couple has been also calculated and we have evaluated the heterogeneous charge transfer rate constant (K⁰).
