Electrochemical Study of 6-(ferrocenyl)hexanethiol on Gold Electrode Surface in Non-aqueous Media

The electrochemical modification of gold (Au) electrode with 6-(ferrocenyl)hexanethiol (6FcHT) is examined by using of cyclic voltammetry technique in the potential range −0.2 V/ + 0.5 V at the scan rate of 100 mV/s at 30 cycles in non-aqueous Electrochemical measurements were performed at different Au electrode surfaces. Bare and 6-(ferrocenyl)hexanethiol-modified gold electrodes (bare-Au and 6FcHT/Au electrodes, respectively) were characterized by four methods which are cyclic voltammetry and electrochemical impedance spectroscopy, scanning electron microscopy (SEM), contact angle measurement (CAM). This study, in which electrochemical studies of 6-(ferrocenyl) hexanethiol were carried out in non-aqueous medium showed very little adsorbed of thiol group on gold electrode surface.
