| Abstract: | The formation kinetics of the self-assembled monolayer (SAM) of an azobenzenealkanethiol, denoted as AzoC2SH on surface was studied using electrochemical techniques, and the monolayers prepared at different assembly times and concentration were also investigated. A two-step adsorption kinetics has been confirmed: the fast adsorption process and the following long-term reorganization. The equilibrium constant(K)for the adsorption and the interaction factor between adsorbate-adsorbate molecules (δ) were evaluated based on the Frumkin isotherm and determined to be (3. 17±0. 13)× 106 mol•L(-1) and -0.34±0.04, respectively. The Gibbs free energy (G)of SAM was determined to be -(37. 07±0. 13)kJ•mol(-1). |
