Solvent-induced SC–SC transformation within the ZnII–triazole system: a promising MnO4− selective luminescent probe

Abstract

A series of coordination polymers based on the ligand tris(4-(1H-1,2,4-triazol-1-yl)phenyl)amine (TTPA) have been developed. Amongst these, complexation with Zn²⁺ results in a 1D ladder complex. The solvent-induced SC–SC transformation within the Zn²⁺–triazole system has resulted in a unique solvate, generating {[Zn(TTPA)(NO₃)₂]·2CHBr₃}_n (4a). Compound 4a was tested for both cation and anion capture of important industrial pollutants. The luminescence properties of 4a indicated that it could be considered as a new triazole based selective luminescent probe for both Pb²⁺ and MnO₄⁻.
