Abstract

The oxidation of tritane dyes at a stationary glassy carbon electrode in methylene chloride is studied using voltammetry. It is shown that electron-donor-type dialkylamino-groups in the dye molecules favor the decreasing of the oxidation half-wave potentials; by contrast, the strong electron-acceptor-type nitroso-group contributes to their increasing. The Cl anion and complex anion In Cl4, which are constituents of triphenylmethane dyes, are not oxidized in these conditions.
