Redox-state investigation in a Co(II) framework with the redox-active tris(4-(pyridin-4-yl)phenyl)amine ligand

Abstract

The synthesis, redox and spectral properties of a Co(II) 3D coordination framework, consisting of interpenetrated 2D (4,4′)-nets with the redox-active tris(4-(pyridine-4-yl)phenyl)amine (NPy3) ligand is reported. The accessible redox states in the framework were explored through solid state electrochemical and spectroelectrochemical experiments. The incorporation of a redox-active metal in conjunction with a redox-active ligand provides access to a greater number of accessible redox states within a solid state material. This strategy holds promise for the synthesis of multifunctional materials that are capable of changing their properties as a function of the electronic state.
