【摘要】 采用溶剂热方法,以柔性三羧酸配体4,4′,4″-（2,4,6-三甲基-1,3,5-三亚甲氧基苯基）三苯甲酸（H3L）与硝酸镉为前驱体,制备了金属有机骨架化合物（[Cd（HL）（H₂O）₂]·DMF）,进而采用单晶X-射线衍射仪、红光光谱仪、元素分析仪等确定了该化合物的结构,并通过荧光光谱仪对其发光性质进行了表征。结果表明,该金属有机骨架化合物中金属中心和配体形成一维链状结构,进而在π-π堆积作用的存在下形成二维层,最后借助层与层之间的氢键连接形成具有三维网络结构,由此制得的金属有机骨架化合物在紫外光照射下可发射蓝色荧光。更多还原

【Abstract】 A new metal organic framework（MOF） was constructed by using a flexible tricarboxylate ligand 4,4′,4″-（2,4,6-trimethylbenzene-1,3,5-triyl）tris-（methylene）]tris（oxy）}tribenzoic acid（H₃L）and Cd（NO₃）₂·4H₂O via solvothermal reaction towards [Cd（HL）（H₂O）₂]·DMF.Metal-oxygen polyhedron and partly deprotonated ligand（HL）^2- were bridged to generate 1D-chain structure.A 2D layer was formed by interconnecting the neighboring chains through π-π interaction,followed by the formation of the 3D network via hydrogen bonding.Fluorescence analysis reveals that the MOFcan exhibit strong luminescent property.更多还原
