摘要
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 three-dimensional（3D）lanthanide coordination polymer Tb2（suc）3（H2O）2·H2O（suc=succinate dianion）was synthesized hydrothermally by the reaction of terbium nitrate hexahydrate with succinic acid.The compound was characterized by single-crystal XRD,IR,TGA and PL.X-ray study shows this compound crystallizes in monoclinic space group C2/c and exhibits three-dimensional open framework.The compound emits green emission with the main peak around 544 nm,which originates from5D4→7F5transition of Tb3＋.
