A bifunctional luminescent Tb(III)-metal-organic framework by a tetracarboxylate ligand for highly selective detection of Fe3+ cation and Cr2O72- anion

A new Tb-MOF(1) with 3D (5,6,8)-connected framework was synthesized under solvothermally conditions. More importantly, 1 reveals highly selective detection of Fe3+ and Cr2O72-, which may be used as chemical sensor in sensing system. Furthermore, the luminescent sensing mechanisms of differentiating analytes are explored in detail239
