Abstract

The electrochemical behavior of octadecanethiol self_assembled monolayers modified gold electrode in different concentration of Fe(CN) 3-/4- 6 is investigated by cyclic voltammetry and electrochemical impedance spectroscopy .It is determined that the apparent he_terogeneous rate constant k s is in the order of 10 -6 cm·s -1 ,the apparent electron transfer coefficients are 0.15 and 0.22.The apparent effective thickness of the SAMs is established which can be used to describe the molecular ordering degree of self_assembled monolayers.
