摘要
以柔性1,3,5-三(4-羧酸苯氧基)苯(H3TCPB)为配体,以4,4′-联吡啶(4,4′-BPY)为辅助配体,在溶剂热条件下合成了2个新颖的分别具有三核锌簇和三核钴簇的金属有机骨架化合物:{[Zn3(TCPB)2(4,4′-BPY)]·DMF·3H2O}n(1)和{[Co1.5(TCPB)(DMF)(H2O)]·DMF}n(2),通过单晶X射线衍射,红外光谱,元素分析,热重分析和粉末X射线衍射对其结构进行了表征。单晶X射线衍射分析表明化合物1属于三斜晶系,P1空间群,表现出三维(3,8)连接的网状结构,拓扑符号为:{43}2·{46·618·84}·{6};化合物2也属于三斜晶系,P1空间群,为二维(3,6)连接的网络层状结构,拓扑符号为:{43}4·{46·618·84}。此外,荧光性质研究表明固态化合物1在室温条件下发射出源于TCPB3-和4,4′-BPY配体的淡蓝色荧光,而化合物2在相似的条件下没有荧光发射。
Two novel metal-organic frameworks {[Zn3（TCPB）2（4,4＇-BPY）]·DMF·3H2O}n （1） with trinuclear zinc cluster units and {[Co1.5（TCPB）（DMF）（H2O）]·DMF}n （2） with trinuclear cobalt cluster SBUs, have been prepared under solvothermal conditions based on flexible 1,3,5-tri（4-carboxyphenoxy） benzene ligand （H3TCPB） with the help of ancillary bridging N-donor pyridyl linker 4,4＇-bipyridine （4,4＇-BPY）, and characterized by single crystal X-ray diffraction, IR spectra, elemental analyses, thermogravimetric analyses （TGA） and powder X-ray diffraction （PXRD）. The single crystal X-ray diffraction analysis reveals that complex 1 crystallizes in triclinic space group P1 and exhibits three-dimensional （3D） （3,8）-connected network with Schlfli symbol of {43}2·{46·618·84}·{6}, complex 2 also belongs to the triclinic system with space group of P1 and shows two-dimensional （2D） （3,6）-connected net-like layered framework with Schl？fli symbol of {43}4·{46·618·84}. In addition, the study of the solid state photoluminescent property of complex 1 indicates that it emits light blue fluorescence arising from TCPB3- and 4, 4＇-BPY ligands at room temperature, while complex 2 is non-emissive under similar conditions.
