| 摘 要： | 合成了以稀土镝为中心离子,以苯甲酸、卤代苯甲酸及邻菲啰啉和2,2'-联吡啶为配体的五种固态配合物。对配合物进行了稀土络合滴定,C、H和N的元素分析、紫外光谱、红外光谱和荧光光谱测定,推测其组成分别为Dy (BA)3(bpy)、Dy (BA)3(phen)、Dy(ClBA)3(phen)(EtOH)、Dy(BrBA)3(phen)(EtOH)和Dy(IBA)3(phen)(EtOH)(BA=苯甲酸根,bpy=2,2'-联吡啶,phen=邻菲啰啉,ClBA=对氯苯甲酸,BrBA=对溴苯甲酸,IBA=对碘苯甲酸);苯甲酸羧基氧、邻菲啰啉和2,2'-联吡啶的氮原子与镝离子配位。配合物都具有较强的荧光,卤代苯甲酸配合物呈现规律发光,对氯苯甲酸-邻菲啰啉-镝配合物的发光效果较其它两种配合物强,对溴苯甲酸配合物又强于对碘苯甲酸配合物;苯甲酸-邻菲啰啉-镝配合物荧光强于苯甲酸-2,2'-联吡啶-镝配合物。

| Abstract: | Five complexes of dysprosium were synthesized,in which benzoic acid or halobenzoic acids were as the first ligand,and nitrogen-heterocyclic(phenanthroline or 2,2'-dipyridine) as the second ligand.By elemental analysis,rare earth coordination titration,the compositions of the complexes were confirmed to be Dy(BA)3(bpy),Dy(BA)3(phen),Dy(ClBA)3(phen)(EtOH),Dy(BrBA)3(phen)(EtOH) and Dy(IBA)3(phen)(EtOH),(BA=benzoic acid,ClBA=p-Cl-benzoic acid,BrBA=p-Br-benzoic acid,IBA=p-I-benzoic acid,bpy=2,2'-dipyridine,phen=... |
