Design, Synthesis And Adsorption Properties Of Novel Metal Organic Frameworks Of Porous Materials

Metal organic Frameworks (MOFs) are the most popular research topic in thecrystal engineering of. Porous materials are a kind of new polymer materials that areinfinite metal complexes and bodies through the skeleton structure of the coordinationbond connection. The content of this paper is as follows:Starting from the crystal engineering, through the design of organic ligands, andthe metal center set up a metal organic frameworks, and hope to get an ideal modelwith the same metal organic framework compounds. Therefore we use the organicligand to synthesize the novel structure, excellent properties of metal organicframework compounds; Also, using the perylene derivative as monomer andmacromolecular organic compounds, synthesized by small molecule organiccompounds with Br functional monomer Suzuki reaction to get conjugated polymers;In addition, we use the hydrothermal method to get a three dimensional porous metalorganic framework materials through synthesizing related ligands. This thesis ismainly for the synthesis of organic ligand, conjugate microporous polymer synthesis,as well as the mixed metal organic framework compounds preparation, which hascarried on the exploration and research. Mixing the synthesis and preparation of metalorganic framework materials is the focus in the study of this thesis. Based on theresearch, we want to synthesize the new structure and good properties of metalorganic framework materials, which can provide some exploration on the basis of thisareas. We will provide certain theoretical basis and methods for the organic synthesis,hydrothermal, metal organic skeleton ligand, and the new type of multifunctionalorganic skeleton materials, and we think we can find a better structure of suchmaterials in the future with excellent performance.First, perylene is a potential macromolecular organic compounds that has manyexcellent properties, we want to use perylene as raw material for synthesizing itsderivatives. By relevant reference, we found that using the perylene to synthetize the2.5.8.11-4methyl benzoic acid is a good method. We think that we can use theorganic ligands to synthesize metal organic framework materials. Second, in the process of synthesis the2.5.8.11-4methyl benzoate, we found thatthe product can be synthesized by the2.5.8.11-4boric acid-base and small moleculeorganic monomer containing Br functional groups through the Suzuki reaction so thatwe can get macromolecule conjugated polymers, which can be analyzed by the X-raypowder diffraction, thermal stability, adsorption properties.Third, in recent years, many reports are using the four ligands and dicarboxylicacid ligand to synthesis of MOFs, thus we hope to find a kind of ligands whichcontain four azole nitrogen functional groups and dicarboxylic acid functional groups.We found that the reports used the ligand is3,5-phthalate tetrazolium. From myperspectives, we found an organic ligand5-(4-four nitrogen imidazolyl)-phenylisophthalic acid, which is more than a benzene ring. Metal organic frameworkcompounds can be synthesized using the organic ligand, and its properties areanalyzed in detail.Because structural stability of the metal organic framework materials (MOFs) isnot very good, these are restricted in many application fields. We hope that we can getthe stable metal organic framework materials by changing its synthetic conditions ormetal center, and the materials can have excellent adsorption properties.
