Hydrothermal Synthesis Of Decavanadium Oxide Complex With 1,10-phenanthroline

Recently, coordination polymers and supramolecular architectures formed through the deliberate selection of metals and multifunctional ligands have received much attention for their fascinating structural diversity and specific functionality, which have made them highly promising in various applications, particularly absorption, catalysis and molecular magnetization.We select the chelated ligand as 1,10-phenanthroline which possessing the N atom with strong coordinated ability. Two N atoms from the didentate ligand 1,10-phenanthroline may occupy two coordination positions of metal ions, thus the feasibility of coordination is counteracted at space, and it can be synthesized low dimensional or layer compound. We have synthesized several coordinated polymers with these ligands above using hydrothermal motheds, and the synthesis and characterization of the coordination complexes are introduced detailedly in this thesis. It is divided into five chapters.In the first chapter, one briefly introduce about the concept and development of coordination polymers are given, as well as one briefly introduce about the research progress of phenanthroline's coordination complexes and the concept of hydrothermal synthesis are given, as well as the current survey, research significance in this thesis, and at last, we discuss the current survey, research significance and the results in this thesis.In the second chapter, three different polymeric cobalt(â…¡) vanadium(â…¤) complex constructed with 1,10-phenanthroline has been hydrothermally synthesized and described: [Co^â…¡(phen)₂]₂V₄O₁₂, [Co^â…¡(phen)₃].[V₄O₁₂]·10H₂O and [Co^â…¡(phen)(H₂O)V₂O₆]_n.In the third chapter, one polymeric nickel(â…¡) vanadium(â…¤) complex constructed with 1,10-phenanthroline has been hydrothermally synthesized and described: [Ni^â…¡(phen)₃]·[V₄O₁₂]·17.5H₂O.In the fourth chapter, a concise conclusion about this work and an outlook are presented.
