【摘要】 以一种V型3,5-二（4-羧基苯基）-4-苯基-1,2,4-三唑（H₂PhTz）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（H₂O）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。更多还原

【Abstract】 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 Ph Tz represents 4,4’-（4-phenyl-4H-1,2,4-triazole-3,5-diyl） dibenzoate anion,which were characterized by the single-crystal X-ray diffraction 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. 385 nm with the half peak widthwhich is tentatively assigned to the π*→π electronic transitions of the ligands in MOF_Nd.更多还原
