| Abstract: Under hydrothermal conditions, a coordination polymer {[Cu2(Hdepa) (2, 2'-bpy)2(H2O)2] ·2H2O}n was designed and synthesized based on ligands H5depa and 2,2'-bpy (H5depa=2,2',3,4',5-diphenyl ether pentacarboxylic acid, 2,2'-bpy=2,2'-bipyridine). Its structure was characterized by elemental analysis, infrared spectroscopy, singlecrystal X-ray diffraction, and thermal stability analysis. The two central Cu2+ ions in coordination polymer 1 adopt a five-coordination with triangular bipyramid geometry. The incompletely deprotonated Hdepa4- ligand adopts a μ4-η1-η1-η1-η1 coordination mode. The 2D layers are connected by weak hydrogen bonds to form a 3D supramolecular structure. As a highly sensitive, selective, and multi-response fluorescent sensor, 1 could rapidly detect Fe3+ and p-nitrophenol (4-NP). In addition, the fluorescence quenching mechanism was also studied. |
