The self-assembly and electrochemical properties of mixed self-assembled monolayer (SAMs) of 4-methoxy-4_-(N-(2__-mercaptoethyl)amino)carbonyl)azobenzene (C1AzoC2SH) and 1-butanethiol (C4SH) were studied on the gold electrode by cyclic voltammetry. Usually the azobenzene groups exhibit very sluggish electron-transfer kinetics in the densely packed films. The alkanethiol as the spacer molecule was introduced to the azobenzene monolayer system to weaken the intermolecular interaction in order to enhance the electrochemical activity of the azobenzene group. Under the different molar ratios of C1AzoC2SH and C4SH we obtain a different electrochemical response and an apparent surface electrochemical rate constant. The experimental results suggested that the azobenzene groups exhibit a higher electrochemical activity in the mixed SAMs systems.
