Metal-organic coordination polymers have received extensive attention due to the structure of its diversity and potential applications. These polymers, we use multi-carboxy organic ligands and metal ions to form a one-dimensional, two-dimensional, three-dimensional network of infinite covalent bond, hydrogen bonds and other non-price key weak role can be used to form a network of hydrogen bonds. Metal organic coordination polymer materials (MOFs) as a new type of porous material, not only in the field of porous materials with a wide range applications, such as gas storage, separation, catalysis, and their properties can be through a directional center of the choice of metal ions and organic functional groups to regulate this material in the field of optical, electrical, magnetic, and chiral separation demonstrate a more attractive prospect. The polydentate ligand of nitrogen and oxygen the detailed overview complexes. A dozen of coordination compounds by elemental analysis, X-ray single crystal diffraction, infrared spectroscopy, XRD analysis testing methods to characterize the structure of coordination compounds synthesized by hydrothermal method, solvothermal solution method, diffusion method . And selective determination of the fluorescence properties of the complexes, electrochemical properties, thermal stability. The paper is divided into six chapters. Chapter foreword, a concise description of the of microporous MOFs Development and Research, discussed the significance of the topic of this issue, and reviewed the progress made by this topic. The second chapter describes the 5 - methyl-3 - picolinate and pyrazolyl picolinate ligand 4,4 '- bipyridine, 2,2' - bipyridine ancillary ligands directed to build a seven coordination polymers of hydrophilic or hydrophobic main water clusters guest molecules. The shapes of the object water molecules, a dimer, trimer, hexamer, 10 dimer, in morphology exhibit spiral chain structure, the structure of the molecular layer, the cage-like structure, and through the hydrogen bonds and other non- the role of valence bond weak link. Chapter III describes by controlling the size of the organic ligand 4,4 '- dicarboxy ether, terephthalic acid, linked phthalate, control the number of nodes and the coordination number, select the appropriate template reagent effective control of five synthesized microporous coordination polymers directed to build a five microporous MOFs [of Cu 2 (oba) the 2 · (DMF) 2 (H 2 O), [Cu 2 (4,4 '-bpy) 5 (H 2 < / sub> O) 4 ] (ClO 4 ) 4 (4,4 '-bpy) (DMF) 2 (H 2 O) 2 (10), Na 2 K [Cd 3 (tpca) < sub> 6 (DMF) 2 ] (12), Na [Cd 2 (bdca)] (13). With the aperture of the change in length of the ligand with the change, the corresponding volume changes. Under a nitrogen atmosphere at 200 degrees is not collapsed, having a very high stability, which is very important for the microporous material. Chapters IV and V of 4,4 '- dicarboxy diphenyl ethers coordination polymers. In addition to choose flexible bridging ligand, we also selected as a second ligand chelating ligands such as 2,2 '- bipyridine and phenanthroline phenanthroline, etc.. And hydrogen bonds, π-π accumulation, the role of non-covalent bonds weak role in the structural stability. Chapter dozen pyrazole derivatives ligand and the corresponding rare earth complexes were synthesized and systematic analysis of the luminescence properties of the dozen complexes, and the effects of selection morpholine phenanthroline as a sensitizer to the luminous performance impact, its luminous intensity is 30% stronger than Carmen agent. And prepared a the polymer microspheres parcel efficient fluorescent probe to stronger fluorescence properties.
