摘　　要：以一种V型3,5-二(4-羧基苯基)-4-苯基-1,2,4-三唑(H_2PhTz)为有机配体通过溶剂热法合成出一种金属-有机框架化合物[Nd(PhTz)_(3/2)(H_2O)_2]_n(MOF_Nd),其中,Ph Tz是3,5-二(4-羧基苯基)-4-苯基-1,2,4-三唑的二价阴离子。利用单晶X-射线衍射、粉未X-射线衍射及红外吸收光谱等分析手段表征了MOF_Nd的分子结构与纯度。X-射线单晶衍射分析表明含有1维孔道结构的MOF_Nd单晶属于的三斜晶系的P1空间群。MOF_Nd的固体粉末在紫外光的激发下,能发出位于385nm的半峰宽为48nm的荧光峰,该荧光发射被归为配体的π*→π电子跃迁。A V-shaped 4,4′-（4-phenyl-4H-1,2,4-triazole-3,5-diyl）dibenzoic acid （H2PhTz） was designed and used to synthesis solvothermally a metal-organic framework of [Nd2（PhTz）3（H2O）4]n （MOF-Nd）, where PhTz represents 4, 4＇-（4-phenyl-4H-1,2,4-triazole-3,5-diyl） dibenzoate anion, which were characterized by the single-crystal X-ray dif- fraction analysis, powder X-ray diffraction analysis and the infrared absorption spectra. The single-crystal X-ray diffraction analysis suggests that MOF-Nd crystals possess the 3D architecture with the parallel 1D channels. The powder samples of MOF-Nd could give out, under the excitation of UV-light, the fluorescence at ca. 385nm with the half peak widthwhich is tentatively assigned to the π＊→π electronic transitions of the ligands in MOF-Nd.
