Solvent-Induced SC-SC Transformation within the ZnII-Triazole System: A Promising MnO4- Selective Luminescent Probe

A series of coordination polymers based on the ligand tris.4-(1H-1,2,4triazol- 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] center dot 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-.
