Abstract:

The incorporation of aminopyridine-ligated cobalt (III) phthalocyanine complex [CoIIIPc(ampy)2]SCN (Pc = pthalocyanine, ampy = aminopyridine, SCN = thiocyanate) to titanium doxide (TiO2) is a promising solution for the oxidation of organic air pollutants in indoor environment. The synthesis involves the oxidation of the cobalt (II) central metal from cobalt (II) phthalocyanine (CoIIPc) and a subsequent ligand substitution yielding KCoIIIPc(SCN)2. A dissociation mechanism substitutes the SCN- ligands for the aminopyridine which attaches to the axial positions of CoIII via its pyridine moiety. The synthesis of the final product was confirmed using various characterization techniques.
