利用线型苯羧酸配体1，4-二（4-羧基苯基）苯（H₂tpdc）构筑金属有机框架（MOFs）。基于单一配体策略，在溶剂热条件下成功构筑了3例无色透明晶体。其中化合物[Cd （tpdc）]·3DMF （化合物1）是一种新型高穿插MOFs，在5次穿插后孔隙率仍高达57.5%。通过X-射线单晶衍射仪对该化合物进行表征，并对其热稳定性及荧光性质进行研究。结果表明，该晶体属于单斜晶系，化合物1结晶在单斜晶系P2/c空间群；晶胞参数为：a=0.157 89 nm，b=2.484 3 nm，c=2.637 2 nm；化合物的单晶结构中Cd离子采用三角十二面体配位构型。化合物1的最大发射峰位于360 nm处，相比配体H₂tpdc的固态荧光最大峰红移34 nm。

1, 4-Bis (4-carboxyphenyl) benzene [H₂tpdc], a linear benzene-carboxylic acid ligand, is used to construct metal-organic frames (MOFs).Based on the single ligand strategy, three examples of clear and colorless crystals are constructed under solvothermal conditions.Among them, [Cd(tpdc)]·3DMF (compound 1) is a new type of high interpenetration MOFs, which has a high pore rate of 57.5% after five-fold penetration.It is characterized by means of X-ray excitation emission spectroscopy, and its thermal stability and fluorescence properties are studied.It is verified that this crystal belongs to the monoclinic system, and compound 1 crystallizes in the P2/c space group of the monoclinic system.The cell parameters are as follows:a=0.157 89 nm, b=2.484 3 nm, c=2.637 2 nm.In the single crystal structure of compound 1, Cd ion adopts the trigondodecahedral coordination configuration.The strongest emission peak of compound 1 locates at 360 nm, and the strongest fluorescence peak redshift of compound 1 is 34 nm compared with that of ligand H₂tpdc.
