Tb配合物的水热合成、晶体结构及荧光性质
TQ413.21; 以1,3,6-萘三磺酸钠(Na3L)、4,4′-联吡啶(4,4′-bipy)、Tb(NO3)3·6H2O为原料,通过水热合成反应制备了Tb配合物[Tb(H2O)8]·(L)·2(4,4′-bipy)·3H2O(配合物1).利用单晶X-射线衍射、傅里叶红外光谱、热重分析以及元素分析等表征手段,分析了配合物1的分子结构和组成,并且研究了其热稳定性和荧光发射性质.结果表明,Tb3+是八配位,呈四方反棱柱配位构型,与8个H2O分子配位形成[Tb(H2O)8]3+;L3-没有与金属离子配位,只平衡了分子内的正电荷;L3-的磺酸基与配位H2O分子之间形成氢键,将[Tb(H2O)8]3+...
