Resumen
The theory of cyclic voltammetry of facilitated proton transfer-electron transfer coupled reactions (FPT-ET reactions) in a thick organic film modified electrode is developed. It is shown that the coupling between the facilitated proton transfer-electron transfer processes has a marked effect on the shape of the current-potential profiles. The model allows the analysis of the system in different experimental conditions, such as pH and concentration ratios between the redox probe and the transferring protonated species. This model for proton transfer assisted by different neutral weak bases in a two polarized interfaces system is compared to our previous results for a single polarizable interface. Finally, considerations regarding the application of the thick-film setup are discussed.
