三脚架型配体、配合物的合成及荧光性质

为了进一步研究配体结构对稀土离子配位行为的影响，合成了以N为中心的三足配体——2，2′，2″-三（2-苯胺基甲酰基苯氧基）三乙胺（L）及其稀土硝酸盐配合物．试验表明，在合成三（2-氯乙基）胺盐酸盐时，应先用适当的溶剂（如苯）溶解三乙醇胺盐酸盐，然后向其中缓慢滴加氯化亚砜，并在合成N-苯基水杨酰胺的过程中，用DCC作脱水剂，效果较好．该合成方法明显降低了氯化亚砜的挥发，减少了原料损失，使操作条件更温和。收率可达80％以上：在室温下．铽配合物表现出Tb^3＋的特征荧光发射峰．

Synthesis of a tripod-type ligand and fluorescence properties of its rare earth complexes

In order to the effects on Ligand structure to the property of rare earth complexes, a new ligand -2, 2′,2＂-tris （2- phenylamine-carbonyl-phenzoxy） tri-ethylamine and their rare earth complexes were synthesized and their fluorescence properties were investigated, The test showed： the optimum processes of the synthesis of ligand were that tris（nitro-phenoxyethyl） amine hydrochloride salt was dissolved by benzene, then thioyl chloride was dropped into and the selected dehydrating agent should be DCC in the synthesis of N-phenyl-salicylamide. It was found that the methods of synthesis is easy to control and reduce the wastage of thioyl chloride. The production yield was up to 80%. The Tb-complexes exhibited characteristic fluorescence emission peak.
