Anderson-type polyoxometalate-based complexes constructed from a new ‘V’-like bis-pyridine–bis-amide ligand for selective adsorption of organic dyes and detection of Cr(vi) and Fe(iii) ions

Abstract

Four isostructural complexes constructed from Anderson-type POM and new ‘V’-like ligands exhibited outstanding selective adsorption capacities for organic dyes, and electrochemical sensing behaviors toward Cr(vi) and Fe(iii) ions.
