Synthesis, Structures And Properties Of The Coordination Polymers Based On Nitrogen-containing Carboxylic Acid Ligand

Porous coordination polymer has both a strong bonding effect contains weakintermolecular interactions such as hydrogen bonds, Ï€-Ï€ interaction, such structurallydiverse compounds. Due to the porous coordination polymers also have the dualcharacteristics of the organic polymer and inorganic metal, is a novel and uniquenature of the material, has a good prospect of application in many aspects ofcatalysis, molecular recognition, magnetic materials, fluorescent materials, hydrogenstorage materials and conductive materials, has become the coordination chemistryone of the hot topics of the research field. In this thesis through the selection ofbenzotriazole-5-Carboxylate Ligand, transition metal ions and nitrogen-containingorganic ligands as ancillary ligands solvothermal synthesis and synthesis of a seriesof new coordination polymers, and through elemental analysis, IR, TGA, X-raydiffraction, XRD the characterization of these synthesis of coordination polymersand the Ministry allocated polymer adsorption and magnetic properties.The first chapter briefly introduced, and some of the latest research progress ofporous coordination polymers the representative porous coordination polymerstructure, nature and applications were summarized.In the second chapter, we used H2btca with Mn（II） ion，an ancillary ligand4,4’-bpy via a solvothermal method, synthesized two new porous coordinationpolymer，Mn₆（btca）₄（H₂O）₂·（EtOH）₂·bpy·DMF（1）,Mn₆（btca）₄（H₂O）₂·（EtOH）₂·4H₂O（2）.Complex1is a3D porous coordination polymerwhich has a1D square channel connected btac ligand and {Mn-OH-Mn}nchains.Complex2is connected btca with six-core manganese cluster and the formation ofthree-dimensional polymeric complex containing one-dimensional square channel.In the third chapter, synthesis two3D porous metal-organic frameworkMn₃（btca）₂（DMF）·（H₂O）₂·H₂O·DMF （3）;Zn₆（btac）₄（H₂O）₂·（EtOH）·DMF·2H₂O （4）.The uncoordinated molecules filled in the square pore. Complex3and4which arebridged with Mn,Zn and3-OH groups to form extended {Mn-OH-Mn}nand {Zn-OH-Zn}nchain. The btca ligands linked with extended {Mn-OH-Mn}nand{Zn-OH-Zn}nchains which connected to form a three-dimensional polymericcomplex.In the fourth chapter, four coordination polymers synthesized with a summaryof the solvent, auxiliary ligand on the synthesis of complexes, which provides a newapproach for the synthesis of novel structure.
