摘　　要：以2-氨基-4-氯苯甲酸(2-A-4-CBA)作为第一配体,1,10-邻菲罗啉(phen)作为第二配体,采用溶剂热法合成稀土铽离子(Tb^(3+))的三元有机配合物.通过元素分析、红外光谱及热重分析确定了配合物的化学结构,结果表明:配合物可表示为[Tb(2-A-4-CBA)phen(H_2O)4·H_2O],2-氨基-4-氯苯甲酸和1,10-邻菲罗啉均参与配位且配合物具有较高的热稳定性;通过紫外光谱、荧光光谱、色坐标研究配合物的发光性能,配合物发出较强的Tb3+的特征荧光,在369.6 nm激发下其最强发射峰在545.2 nm处,其色坐标落在黄绿光区域.In this study, a novel organic ternary complex of terbium was synthesized using 2-amino-4- chlorobenzoic acid （2-A-4-CBA） as the first ligand and 1,10-phenanthroline （phen） as a secondary lig- and under solvothermal conditions. The molecular formula of complex was confirmed by elemental analysis, IR spectroscopy and thermogravimetric/differential thermogravimetric （TG-DTG） measurements. The results show that 2-amino-4-chlorobenzoic acid and 1,10-phenanthroline are coordinated to Tb^3＋ and the formula of complex can be written as [ Tb （2-A-4-CBA）phen （H20） 4· H2O], the complex exhibits better heat endurance. The optical properties of complex were measured by ultraviolet spectroscopy （UV）, fluorescence spectroscopy （FS） and CIE coordinates. The results indicate that the complex emits characterstic luminescence of Tb^3 ＋ ion with main peak at 545.2 nm on excitation at 369.6 nm. The CIE chromaticity coordinates of the complex are in the yellow-green region.
