Synthesis And Application Research Of Diphenylphosphinate And Cyanopyridine Amidinate Compounds

Recently, the most important subjects of intensively current research in the field of coordination chemistry, supramolecular chemistry, crystal engineering and material have focused on building novel metal-organic supramolecular compounds through metal-ligand coordination and intermolecular interactions between ligands. Design and synthesis of polynuclear, heterometallic and helical metal-organic supramolecular complexes with novel topological structures or special properties is have great interest at present, due to their ability to impart nonlinear optical, electrochemical, catalysts, magnetics, molecular devices, highly selective and specific molecular transformations, transport, storage and polymorphism.This thesis covers following four parts:Chapter 1:In this part the concepts of coordination chemistry, supramolecular, crystal engineering and coordination polymer were simply introduced. The structural research approaches, along with the significance and application of the study, were also discussed.Chapter 2:The reaction of LiN(SiMe3)2 with 2,3,4-cyanopyridine in the ratio of 1:1 were carried out, two compounds:2a and 2b were prepared. Treatment of 2a with half equivalent anhydrous zinc chloride gives the compound 2c. The molecular structures of these compounds were determined by single crystal X-ray diffraction.Chapter 3:Under the high temperature high pressure condition, with the diphenylphosphine(L) and the anhydrous calcium chloride/magnesium acetate responded in the alcohol solvent that synthesizes coordinate polymer 3a,3b. The molecular structures of these compounds were determined by single crystal X-ray diffraction. Similarly, the amorphous fibrous diphenylphosphinate coordination polymer 3c,3d,3e,3f,3g,3h,3i,3j,3k were synthesized with L and different metal salts. The structures and properties of 3c-3k were measured by Powder X-ray diffraction spectrum, X-ray photoelectron spectroscopy, magnetic, TG-DTG, Field-emission SEM and so on. The coordination polymers 31-3n were measured by similar approach.Chapter 4:Give the contents summarize of Chapter 1-3. The rule in the process of synthesis forβ-diketiminatometal metallic complexes, diphenylphosphinate or metallic compounds was submitted. The application of these compounds in materials chemistry was viewed.
