Abstract:As a new type of crystalline porous material,metal organic frameworks(MOFs)have been widely used in the fields of catalysis,bionics,fluorescence,chemical sensing,gas adsorption and separation.A new type of metal organic framework Zn-TDPC(TDPC=diphenylamine tetracarboxylic acid)with TDPC as the bridging ligand and binuclear zinc as the metal node is synthesized by solvothermal method and the yield of ${\left[ {{\rm{Z}}{{\rm{n}}_{1.33}}\left({{\rm{TDPC}}} \right)\left({{\rm{EtOH}}} \right)} \right]_n}$ is as high as 52%.It can be seen from the single crystal diffraction analysis that the frame of Zn-TDPC has a large quadrilateral channel and a small quadrangular channel.And through subsequent analysis such as single crystal diffraction analysis,EA,powder XRD,IR,UV-Vis and TGA,it can be preliminarily judged that the MOF material is a new MOF structure,which is easy to synthesize and has ultra-high stability.There is a wide range of application prospects in the fields of catalysis,gas adsorption and separation.
