摘　　要：通过水热法制备了一个5-(双羧基甲基氨基)间苯二甲酸钴配合物[Co_(3)(HL)_(2)(H2O)_(6)]n·2n H_(2)O (H4L=5-(双羧基甲基-氨基)间苯二甲酸),并用红外线、X-射线单晶衍射技术对其结构进行了表征。固态荧光光致发光测量显示在502 nm处表现出强烈的发射峰,这峰归属于配体内部的特征电子跃迁和分子堆积效应,CIE色差分析表明标题配合物为绿光光致发光(色度坐标为0.059 4,0.641 1)。同时,通过固态UV/Vis漫反射实验,也揭示了该标题配合物具有1.81 e V能量窄带隙。A novel cobalt complex [Co_3(HL)_2(H_2O)6]n·2n H_2O(H_(4L) = 5-(Dicarboxymethyl amino) isophthalic acid) was synthesized via a hydrothermal reaction and characterized by single crystal X-ray diffraction technique.A solid state photoluminescence measurement revealed that there is one strong emission peak at 502 nm.The peak can be assigned to the characteristic electronic transition and stacking effect inside the ligand.The title complex shows CIE(Commission Internationale de I' éclairage) chromaticity coordinates in the green region(0.0594,0.6411).At the same time,the title complex has a narrow band gap of 1.81 eV,which was revealed by a solid-state UV/Vis diffuse reflection experiment.
