Electroactive self-assembled monolayers: Laviron's interaction model extended to non-random distribution of redox centers
Résumé
The Laviron's interaction model, dedicated to randomly distributed electroactive adsorbed species, was extended to a non-random distribution in order to extract the current-voltage characteristics from any surface distribution of electroactive centers on self-assembled monolayer (SAM). Confronted to electro-chemical behaviour of nitroxyl radical SAMs, the agreement observed between theory and experiments provides evidence of a distribution independence of the interaction parameters.
