Abstract
The electrochemical stability of monolayers is important for future applications. A potential window for self-assembled monolayers in aqueous inert electrolyte was obtained using Cyclic Voltammetry, Electrochemical Impedance Spectroscopy and Heterogeneous Electron Transfer. Also electrochemical techniques can be used for sensing applications. We investigated mixed monolayers of ferrocenethiol and an acid alkylthiol. Deprotonation of the acid by an alkaline electrolyte influences the other part of the mixed monolayer. The formal potential of ferrocene is shifted about 150 mV cathodically by the negative charge in the carboxylate part of the layer.
