Hydroxyl (carbonyl) Pyridine Nitrogen Acid Synthesis, Structure And Properties Of Metal Complexes

Recently, crystal engineering of coordination polymer and supramolecular chemistry has become one of the particularly important and topical subjects, and also there are potential applications in the fields of medicine, absorption and selective catalysis, nonlinear optical and magnetic materials. Hence, it is of great importance for the development of supramolecular chemistry and material science to explore the assembly of functional organic ligand with metal ion and to investigate the relationship of the structure and property. In this thesis, the designing three organic ligands, 3-hydroxyl / 2-oxo / 4-oxopyridinoacetic acids, were used to prepare 23 coordination complexes with a great variety of topological structures, including mononuclear, binuclear macrocyclic, 1 -D chain, 2-D layer as well as 3-D network, which were characterized by elemental analysis, IR, TG, PL and X-ray single crystal diffraction. The results show that there are thermal stability and exhibit strong fluorescence. In these complexes, the 3-hydroxyl / 2-oxo / 4-oxopyridinoacetate ligands exhibit as counter-ion, monodentate, bidentate and tridentate coordination modes, and they are excellent building blocks for the construction of the supramolecular system owing to the coordination sites of hydroxyl(carboxy) and carboxylate groups.
