New organic picolylamine-type ligands and electrochemical study of their complexation with Cu(MeCN)4ClO4

Abstract

A series of novel organic ligands with dipicolylamine and disulfide groups connected by polymethylene, alkylaryl, alkoxyaryl, or alkoxycarbonyl linker was synthesized. The electro chemical study by cyclic voltammetry was carried out for two synthesized ligands, and the formation of the complexes with Cu(MeCN)ClO 4 in the solution or on the gold electrode surface was established. The complex of Cu I with 1,24 bis[N,N bis(2 pyridylmethyl) glycinoyloxy] 12,13 dithiatetracosane chemisorbed on the Au electrode is capable of binding molecular oxygen from solution.
