    • note
    • 38 At low electrolyte concentrations in the bulk solution, a minimum of the charging current has been predicted near the peak potential, because the charge at the PET changes in the course of the electrode reaction. This effect is significant for chemically attached films in which redox-active centers are immobile. Our complexes are retained at the electrode surface by physical adsorption due to their limited solubility in water. Mobile electroinactive ions from the bulk solution penetrate into the film. Consequently, the EDL structure in our films resembles that in solutions rather than the EDL in monolayers. Moreover, the concentration of supporting electrolyte in our experiments was high: ≥ 0.1 M (see Table 1). Therefore, simple subtraction of the background current is appropriate in our case.
