We have shown that a molecular theory that explicitly accounts for all the molecular species, the different interactions and the chemical equilibrium is capable of quantitatively predicting the electrochemical behavior of redox-polymer modified electrodes. The theory has predictive power and it is not based on fitting experimental observations. Furthermore, the approach provides with a link between the macroscopic observed behavior and the detailed structure of the polymer layer and therefore it enables the fundamental understanding of the driving force for the observed behavior, while at the same time it can be used as a design tool.
