以六水合硝酸铽和丁二酸为反应物,通过水热合成法获得了一种三维稀土有机配位聚合物Tb2(suc)3(H2O)2·H2O(suc为丁二酸根)。通过单晶XRD衍射、红外光谱、热失重分析及荧光分析等手段对产物进行了表征。单晶衍射结果显示聚合物为单斜晶系,C2/c空间群,具有三维结构。由于Tb3+的5D4→7F5跃迁,化合物的主要发射峰位于544nm处,具有绿色荧光。 A ternary rare earth organic coordination polymer Tb2 (suc) 3 (H2O) 2 · H2O (suc is succinate) was obtained by hydrothermal synthesis using terbium nitrate hexahydrate and succinic acid as reactants. The products were characterized by single crystal XRD, infrared spectroscopy, thermogravimetric analysis and fluorescence analysis. Single crystal diffraction results show that the polymer is monoclinic, C2 / c space group, with a three-dimensional structure. Due to the 5D4 → 7F5 transition of Tb3 +, the main emission peak of the compound is located at 544 nm with green fluorescence.
