Synthesis, Crystal Structures And Photoluminescent Properties Of Metal Coordination Polymers With Imidazole-containing Heterocyclic Ligands

Coordination polymers and supramolecular architectures formed through the deliberate selection of metals and multifunctional exodentate ligands, based upon their coordination habits, have so far spawned tremendous interests in the areas of inorganic chemistry, crystal chemistry and materials chemistry. The fascinating structures of these complexes, coupled with their specific functionality, have made them highly promising in various applications, particularly absorption, catalysis, and molecular magnetization. This work used the simple and easily available organic imidazol -containing compounds for bridged ligands, functional coordination compounds through the crystal structures and properties of series complexes with N-Containing heterocyclic ligands. The thesis is divided into six chapters.In the first chapter, the concepts, methods and histories of coordination polymers are concisely introduced, as well as the current survey, research significance and the results in this thesis.In Chapter 2, the successful design and synthesis of coordination polymers with 1,4-bis(4,5-dihydro-1H-imidazol-2-yl)benzene(bib) are described, in which 0D ring cluster and 3D zigzag are obtained. Furthermore, the investigation of photoluminescent properties of these complexes shows that metallophilicity play important roles on the luminescent emissions.In Chapter 3, the successful design and synthesis of Mn2+ coordination polymers with 2,6-bis(4,5-dihydro-1H-imidazol-2-yl)pyridine(bip).In Chapter 4, a briefly conclusion on this work and an outlook have been viewed.
