摘　　要：通过溶剂热反应成功合成出一种新型2D配位聚合物[Tb(1,4-bdc)_(1.5)(phen)(H_(2)O)]_(n)(1)(1,4-H_(2)bdc=对苯二甲酸;phen=菲咯啉)。对其进行了单晶X射线衍射、粉末X射线衍射、红外光谱、元素分析、荧光光谱表征。X射线衍射晶体学分析表明,配合物1结晶于三斜晶系P1空间群,2个相邻的Tb(Ⅲ)离子与4个1,4-bdc^(2-)通过—O—C—O—桥联成双核单元,并进一步通过1,4-bdc^(2-)桥联成二维层状结构。荧光实验证明配合物1可以通过荧光猝灭机制检测Fe_(3+),Ksv=8.39×10^(3) L·mol-1,检测限为0.017μmol·L^(-1)。Two-dimensional coordination polymer of[Tb(1,4-bdc)_(1.5)(phen)(H_(2)O)]_(n)(1)(1,4-H_(2)bdc=terephthalic acid,phen=1,10-phenanthroline)was synthesized by solvothermal approach.Complex 1 was characterized by single-crystal X-ray diffraction,powder X-ray diffraction,FT-IR spectroscopy,elemental analysis,and fluorescence spectra.X-ray diffraction crystallographic analyses show that complex 1 crystallizes in the triclinic crystal system P1 space group;two adjacent Tb(Ⅲ)ions are bridged by—O—C—O—from four 1,4-bdc^(2-)into a binuclear unit,and further bridged by 1,4-bdc^(2-)into an infinite 2D layered structure.The fluorescence experiment proved that the complex 1 can detect Fe_(3+)through the fluorescence quenching mechanism with K_(sv)=8.39×10^(3) L·mol^(-1) and limit of detection of 0.017μmol·L^(-1).CCDC:2095406.
