Electrochemically active self-assembled monolayers (SAM) of ferrocene (Fc)-terminated alkanethiols on gold surface have been expected for application to sensors and molecular electronic devices. Redox and reductive desorption behaviors of SAM have been well studied in aqueous solutions such as HClO4 aq [1]. However, there are less reports on the electrochemical behavior of SAM in ionic liquid (IL) electrolytes than in aqueous ones. Previously some of the authors reported the redox behaviors of 11-ferrocenyl-1-undecanethiol (FUT) SAM on Au(111) in IL electrolytes. The results suggested that only part of the FUT molecules is involved in the redox reaction. This implies the steric effect by large anions, because they could not assemble around the oxidated Fc +
