Synthesis and Electrochemical Characterizations of 7- Ferrocenycarbonyloxy-1-heptanethiol on Gold Substrates
نویسندگان
چکیده
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, H 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 Fe in solution. The frequency change (interfacial mass change) on the gold electrode surface is observed during the redox of ferrocenyl groups.

A study of the charge transfer and self-assembly characteristics of two new rigid-rod molecular wires 1 and 2 assembled on polycrystalline gold electrodes was carried out using electrochemical impedance spectroscopy and cyclic voltammetry. This class of wires have precisely controlled (ca. 1.5-2.5 nm) lengths of π-conjugation, with extended HOMO and LUMO wavefunctions. While rotations can occur...

Gold nanostar particles were synthesized using seed-mediated method. Au-seed was synthesized with the diameter of approximately 3 nm and a considerably low STDEV of less than 1 nm. Then, different amount of Au seed was introduced into the growth solution of nanostars and the influence of the changes in concentration of Au seed on the growth process was investigated. The size of gold nanostars i...
