摘 要: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Tb3+的特征荧光发射峰.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.
