    Abstract

    Dynamic processes of viologen monolayers at electrified interfaces were described for self-assembled monolayers (SAMs) of viologen-thiols on a Au electrode and the spike voltammetric response of heptylviologen on a HOPG electrode using the results of electrochemical and electroreflectance measurements. We found that the viologen-thiol SAM memorizes anion present while forming the SAM. The spike response of heptylviologen at a HOPG electrode was tentatively assigned as Gibbs monolayer-Langmuir monolayer phase transition.
