“…In our previous reports the electron transfer in the ) and reduction of methylviologen (MV 2 /MV Á ) in Nafion was studied [27,28,41,42]. The electron transfer in the reduction of MV 2 to MV Á occurred by a physical diffusion mechanism, although the redox species are incorporated into the Nafion by a rather strong electrostatic interaction.…”

“…When the MV 2 was anchored onto the polymer framework by a chemical bond, the electron transfer in the reduction of MV 2 to MV Á occurred through a hopping mechanism [42]. In the oxidation of Ru(bpy) 3 2 to Ru(bpy) 3 3 the charge transfer took place by a hopping mechanism [27,28,43], but in the reduction of Ru(bpy) 3 3 to Ru(bpy) 3 2 it took place by a diffusion mechanism [59]. The results indicated that the interaction of the product with the matrix is the deciding factor for the mechanism.…”

“…This film was then placed in an aqueous solution of 4 mM [Os(bpy) 2 Pic] þ for a given length of time. Breaking in of the films, which involves firsttime exposure of the film to the electrolyte was carried out with redox cycling in any given electrolyte at 0.1 V s À1 for 30 cycles, until stable currents were achieved (with 7% increase in electroactivity).…”
