A Highly Sensitive and Multi-responsive Zn-MOF Fluorescent Sensor for Detection of Fe3+,2,4,6-Trinitrophenol,and Ornidazole

A Zinc metal-organic framework(Zn-MOF)based on H4bta(1,2,3,5-benzene tetracarboxylic acid)and bpy(4,4'-dipyridine)ligands,namely{[Zn2(bta)(bpy)(H2O)2]·H2O}n(1),have been hydrothermally synthesized and structurally characterized by elemental analysis,IR spectroscopy,and single-crystal X-ray diffraction analysis.MOF 1 shows a 3D network structure.The completely deprotonated(bta)4-ligand adopts a μ6-η1-η2-η2-η1 chelating and bridging coordination mode.Interestingly,1 is a high sensitivity,good selectivity,and multi-response fluorescence sensor,which can be used for detection of Fe3+,2,4,6-trinitrophenol,and ornidazole.In addition,the thermal stability of 1 was also studied.CCDC:2104032,1.
