Synthesis And Property Of Metal Organic Framework Material Containing Polynuclear Cluster

In this paper, Using different organic ligands and lanthanide metals, transition metals,synthesize complexes with solvent thermal method. These complexes synthesize a total synthesis of two series of rare earth metal organic framework compound containing trinuclear clusters and a five-core copper complexes. Following infrared spectroscopy （IR）, X-ray diffraction analysis （X-ray）, X-ray powder diffraction analysis （P-XRD）, thermal gravimetric analysis （TGA） and other basic characterization techniques to determine the structure of these complexes and performance, and study the fluorescence, magnetic and other properties for its own characteristics of compoundsThesis consists of 3 sections:Chapter 1:The brief introduction of metal skeleton of mailed compound （MOFs） and a brief synthesis of complexes.The development of metal organic framework materials containing polynuclear clusters.Chapter 2:This chapter focuses on p-Phthalic acid （H₂BDC） and 2,6-Naphthalene dicarboxylic acid （2,6-H₂NDC） as the organic ligands and lanthanide metal ions as a metal center. Organic ligandsat synthesized the three-dimensional pore structure of [Ln₃（μ₃-OH）（BDC）₃（H₂O）₉]·3DMF-4H₂O（Ln= Tb, Eu, Dy, Er, Sm, Yb, Gd） （1-7） and [Ln₃（μ₃-OH）（2,6-NDC）₃ （H₂O）₆]·3DMF-5H₂O （Ln=Eu, Tb, Dy, Er, Yb, Gd） （8-13）. studying the structure and properties.of two series of complexes:1-7 complexes are heterogeneous isomorphic, each metal ions center is eight-coordinated patterns, complexes 8-13 are mutually isomorphism body, each metal ions center is seven-coordinated, two series of complexes SUB are three metal ions connected by an oxygen atom μ₃-OH groups form a trinuclear metal cluster, via linear ligands connected, forming a three-dimensional structure with a beautiful hexagonal pore structure. These complexes can be kept relatively complete structural frame at 430℃. Complex 1 has a quenching effect with Fe³⁺ and L-Asp solution, so it can be used to detect and identify Fe³⁺ L-Asp solution, the complex 8 has the same effect to Fe³⁺.Chapter 3:This chpter describes the two-dimensional layered five nuclear copper cluster synthesized by the use of linear organic ligands 4-（1H-1,2,4-triazol-1-yl） benzoic aci[Cu₅（μ₃-OH）₂（L）₄（DMF）₂（H₂O）₂（NO₃）₂]·DMF·H₂O （14） and copper ions to build structure.and study its magnetic areas.
