Synthesis And Catalytic Properties Of Metal Organic Framework Materials With Acid/Alkali Active Sites

Metal Organic Frameworks （MOFs） is a new type of porous material, which is composed of metal ions and organic ligands, and it can be expanded into three dimensional structure. MOFs has been used in many ways, due to its unique aesthetic structure and prominent characteristics, such as high specific surface area （can be extended to 6000m2/g huge surface area）, adjustable crystal structure and hole size, multifunctional applications. MOF is a product of the combination of organic chemistry and inorganic chemistry with the aesthetics of chemical structure. Due to the unique properties of coordination polymers, MOFs has many applications in catalysis, such as light catalysis, catalytic Cyanosilylation reaction, Knoevenagel catalytic reaction, catalytic oxidation, catalytic dehydrogenation reaction and so on.In the first chapter, we introduced the development of the Metal Organic Framework materials,and their application in catalysis.The second chapter, we introduced the coordination polymers 1 is composed of Ni （Ⅱ） and 1,3,5-three （1-imidazolyl） benzene constructed with 3D polymers Ni（tip）2 is a shape for the green oblique parallelepiped. The crystal structure, molecular formula C30H32N12Ni The compound is monoclinic, space group P21/n, a= 11.2986（19） A, b=17.4760 （31） A, c=12.1669 （22） A, γ=108.03（0）°, v= 2284.4 （7） A3. Then let the adsorption of molecular iodine complexes 2 I2∈ Ni （Ⅱ）-MOF. We synthesized the I2 in Ni （Ⅱ） MOF system can be as a high activity of the heterogeneous catalyst, the silicon cyanation of aldehydes catalyzed with mild Conditions.The third chapter, we introduce the coordination polymer 3 is by 5,5’,5"-（1,3,5-triazine Trinitro three amino） 3 benzene dicarboxylic acid and nickel nitratereaction under solvothermal conditions, construction of 3D coordination polymers [Ni9（TDPAT）₂ （μ2-O）₆（H₂O）₉]· 9H₂O of complexes 3 selective catalytic promise the Nagel reaction performance.In the fourth chapter, the catalytic properties of mIm-MOF-14 were studied.The fifth chapter, we summarize the catalytic properties of the synthesized nickel metal organic frameworks, and provide a way for the future research on the catalytic properties of metal organic frameworks.
