Abstract
Glassy carbon (GC) and Au electrodes were modified with aminophenyl films by electroreduction of the corresponding diazonium salt. Aminophenyl films were diazotised using both aqueous and non-aqueous conditions, to generate film-based phenyldiazonium ions. The stabilities of the diazonium terminated films, to exposure to air and in acidic solution, were investigated by cyclic voltammetry (CV). For films of the same thickness, those grafted to Au substrates are more stable than those grafted to GC.
