Synthesis of triethylene glycol-substituted phenylterpyridine with a terminal aurophilic group and its coordination compound with Rh(III) for adsorption on the gold surface

Abstract

A method has been developed for the preparation of a conjugate of 4-substituted phenylterpyridine and lipoic acid with a triethylene glycol linker between the terpyridine and sulfur-containing fragments. A coordination compound of the obtained terpyridine with Rh(III) have been synthesized. The ability of the resulting ligand and rhodium complex to be chemisorbed on the surface of gold electrodes with the formation of an Au-S bond have been shown using the cyclic voltammetry.
