Electroactive self-assembled monolayers: A versatile function to fit symmetric voltammetric peak

•A generalized Gaussian function fits adsorption voltammetric peak.•Drastic experimental conditions are required to such calculations.•This approach is not only dedicated to SAMs but also to a few electroactive layers.

We propose a versatile function to fit adsorption voltammetric peak in order to extract the characteristic parameters such as the full width at half maximum, the peak potential, the peak current and the surface coverage. Based on the generalized Gaussian function and supported by generalized lateral interaction model, this method has been tested on different electroactive self-assembled monolayers (i.e. ferrocene, bithiophene, tetrathiafulvalene and radical aminoxyl units).
