Study On Synthesis And Function Of Coordination Polymer Based On Characteristic Ligand-receptor

Metal-organic framework(MOFs)materials have invaluable research and application value in many fields because of their unique structural characteristics.At present,the application of MOFs is mainly concentrated in the fields of catalysis,gas storage and separation,etc.However,the preparation and research of Coordination polymer and their organic ligands based on donor-acceptor(D-A)structural characteristics are few.In this paper,seven D-A ligands including four carboxylic acid ligands and three pyridine ligands were synthesized.Using these ligands and transition metals,thirteen Coordination polymer were synthesized by self-assembly method.Their structures are determined by means of X-ray single crystal diffraction,and their properties were also studied.?.Seven novel Coordination polymer were designed and synthesized by solvothermal method using three D-A type organic ligands and transition metals.The structures of Coordination polymer are described in detail,and their functions were also studied.?.We designed and synthesized three D-A bidentate pyridine ligands,and obtained three different Coordination polymer by self-assembly.Through X-ray single crystal diffraction,we accurately described the coordination model and geometric configuration of the crystals.What's more,we explored their properties and functions.?.We designed and synthesized a tridentate carboxylic acid ligand,L7,which has the D-A structure,and we synthesized two Coordination polymer using the L7.We analyzed the structure and photophysical properties of the ligands,and characterized the structure and fluorescence properties of Coordination polymer.we synthesized a series of Coordination polymer with new coordination models and geometric structures,and the ligands for building them all have D-A system.We described their structural characteristics and studied their functions.
