Abstract

The 7-ferrocenycarbonyloxy-1-heptanethiol (FcCO2C7SH) is synthesized using ferrocene carboxylic acid, 1,6-fibromohexane, and NaS, which is confirmed and separated by FT-IR, 1H NMR, and column chromatography. The basic redox (interfacial) properties are also studied of the self-assembled monolayers (SAMs) formed with this synthesized compound on polycrystalline gold electrode by Electrochemical Quartz Crystal Microbalance (EQCM). The FcCO2C7SH on gold acts as a barrier for the electron transfer between the gold electrode and HClO4 in solutions and as a mediator for the reduction of Fe3+ in solution. The frequency change (interfacial mass change) on the gold electrode surface is observed during the redox of ferrocenyl groups.
