| 摘要: 合成了一个新的铕（Ⅲ）配合聚合物{[Eu （L）2（H2O）4]Cl3·2H2O}n （1）（L=1，1'-（2，3，5，6-四甲基-1，4-亚苯基）双（亚甲基）双（吡啶-1-鎓-4-羧酸盐））。配位聚合物分子结构经X射线单晶衍射分析确认。对配合物1进行了X射线粉末衍射、红外光谱、热重法和固体荧光光谱表征。固体荧光测试显示配合物1具有非常明显的稀土铕离子特征发光，表明配体能够高效地敏化稀土离子发光。此外，这种水稳定的1被用作化学传感器来检测各种常见的抗生素，发现它对水相中的呋喃西林分子表现出高选择性、高灵敏度和可循环的检测能力。 | |

| Abstract: A novel coordination polymer, {[Eu(L)2(H2O)4]Cl3·2H2O}n (1) (L=1,1'-((2,3,5,6-tetramethyl-1,4-phenylene) bis(methylene))bis(pyridin-1-ium-4-carboxylate)), was synthesized under hydrothermal conditions by a zwitterionic organic ligand and characterized by single crystal X-ray diffraction. Powder X-ray diffraction, IR, thermogravimetry, and luminescence properties of 1 were also determined. The solid-state luminescence properties of 1 were investigated, realizing the zwitterionic ligand is an excellent antenna chromophore for sensitizing Eu3+ ions. In addition, this water-stable 1 was utilized as a chemosensor to detect various common antibiotics to find that this one can exhibit high selectivity, sensitivity, and recyclability in the detection of furacilin molecules in aqueous phases. | |
