| Abstract: A Zinc(Ⅱ) metal-organic framework (Zn-MOF), namely[Zn(H2L)(4,4'-bpy)]n (1), where H4L=1,1'-ethylbi-phenyl-3,3',5,5'-tetracarboxylic acid, 4,4'-bpy=4,4'-bipyridine, was successfully synthesized under solvothermal conditions. The structure was characterized by single-crystal X-ray diffraction, elemental analysis, and thermogravimetric analysis. The single crystal structure analysis shows that 1 belongs to the monoclinic C2/c space group and H2L2- ligands adopt monodentate coordination mode, connecting with Zn (Ⅱ) to form 1D chains. Finally, the 1D chains are connected by 4,4'-bpy to form a 2D wavelike network. 1 shows good stability in water, and can be used as a highly sensitive and selective fluorescent probe to detect tetracycline (TET) with a detection limit of 0.17 μmol·L-1. 1 can be successfully used for the determination of tetracycline in Yanhe River water. In addition, the possible fluorescence quenching mechanisms of 1 were also studied. CCDC:2212375, 1. |
