The Electrochemistry of Micelle‐Solubilized Ferrocene

Abstract

The electrochemistry of ferrocene solubilized by the use of nonionic detergent in aqueous phosphate solutions pH 7.0 was studied. The ferrocene molecules were incorporated as micelles which readily transferred electrons with a platinum electrode. Cyclic voltammetric and potentiometric data indicated that the electron transfer reaction was reversible. Micelle size calculated from electrochemical diffusion and light scattering data gave radii between 40–45Å and molecular weights of ca. 130,000. The ferrocene‐micelle served as an excellent mediator‐titrant to couple electron transfer between an electrode and the heme proteins of cytochrome c, cytochrome c oxidase, and mixtures thereof.
