Highly sensitive fluorescent metal-organic framework as a selective sensor of MnVII and CrVI anions (MnO4-/Cr2O72-/CrO42-) in aqueous solutions.A luminescent ZnII-MOF named TMU-41, [Zn2(BDC)1.5(L)(DMF)]·1.5DMF, (L = pyridine 4-carboxylic acid and BDC = benzene-1,4-dicarboxylate), has been successfully assembled and well characterized by single-crystal X-ray crystallography, thermogravimetric analysis (TGA), X-ray diffraction (XRD) and N2 adsorption-desorption isotherms, which shows good stability especially in aqueous solutions.
