The Controllable Synthesis And Application Study Of Mixed Ligand Based Coordination Polymer

As the representative of organic-inorganic hybrid materials,coordination polymers have been widely used in the field of gas adsorption/desorption,optical materials,electrochemical materials,magnetism,sensing and catalysis via its diverse structure,which is meaning for material science,chemistry and physics.In this thesis,based on rigid carboxylates and different N-donor co-ligand,31 novel coordination polymers with unique structure and dimension have been constructed,and the structural characteristics were studied detailly.There are following six chapters:In chapter 1:A brief introduction of the concept,history and development coordination polymers.The applications of coordination polymer were also selectively introduced.In chapter 2:By using the tetrafluoroterephthalic acid ligand and different N-donor co-ligand to react with Mn,Co,Ni and Zn,seven new coordination polymersweregot,whichwerenameas[Ni（tfbdc）（1,4-bip）_1.5]_n（1）,[Co（tfbdc）_0.5（1,4-bimb）_0.5（H₂O）]_n（2）,[Ni（tfbdc）_0.5（1,4-bimb）_0.5（）H2O]_n（3）,[Co（tfbdc）（bmimb）]_n（4）,[Zn（bimb）（dbbdc）]_n（5）,[Zn（ptl）（dbbdc）H₂O]_n（6）,[Zn（dbbdc）（diyb）]_n（7）.X-ray diffraction structure analysis showed that they are 2dimensional sheets or 3 dimensional frameworks.The structural comparision indicating that the N-donor ligands with different length pay important roles in determining the structure diversity.In chapter 3:By using the amino-,nitro-and hydroxy-modified carboxylate ligand and rigid and semi-rigid N-donor co-ligand,coordination polymers 8-16 were obtained,which were named as[Mn（dabdc）_0.5（ptl）_0.5]_n（8）,[Zn（1,2-bimb）（dabdc）]_n（9）,[Mn₄(L₂₅)₂（bdc）（abdc）₂]_n（10）,[Cd(L₂₄)（abdc）]_n（11）,[Zn（pd）₂（abdc）]_n（12）,[Cd（bmimb）（3-nbdc）]_n（13）,[Cd（1,2-bimb）（5-nbdc）H₂O_]n（14）,[Cu（1,2-bimb）（O-hydroxybenzoicacid）₂]_n（15）,[Cd₂（1,2-bimb）₂（5-hydroxy isophthalic acid）]_n（16）.X-ray diffraction structure analysis showed that their structure ranged from 0 D to 3 D frameworks.In chapter 4:Based on the difference of coordination ability and mode of mono-,di-and tri-carboxylic acid as well as N-donor ligands,complexes 17-24were prepared,which were named as[Cu（bimb）（2-Pyrazinecarboxylic acid）₃]_n（17）,[Zn（1,4-bmimb）_0.5（Phenylaceticacid）（H₂O）_0.5]_n（18）,[Cu（1,4-bimib）_0.5（2-Pyrazinecarboxylicacid）（HCOOH）₂]_n（19）,[Cu₂（1,4-bimb）（2-Pyrazinecarboxylic acid）₆]_n（20）,[Ag₂（1,2-bimb）₂（Phthalic acid）]_n（21）,[Cu（1,2-bimb）（IPA）]_n（22）,[Cu₂（1,4-bmimb）（Dipicolinic acid）₂]_n（23）,[Cu₂（1,2-bimb）（H₃L）（Ac）（H₂O）]_n（24）.The structure of these complexes were also analysised.In chapter 5:By using different inorganic anions(PO₄^3-,SO₄^2-,Cl^-,CO₃^2-)and neutral N-donor ligand to react with transition metal ions（Zn,Cu,Mn,Cd）,complexes25-31wereprepared,whichwerenamedas[Zn₂（1,2-bmimb）（PO₄）₂（H₂O）₂]_n（25）,[Zn₂（1,2-bip）（PO₄）₂]_n（26）,[Mn（SO₄）_0.5（bip）]_n（27）,[Zn（1,2-bmimb）（SO₄）]_n（28）,[Cd₂（SO₄）₂（bmimb）H₂O]_n（29）,[Cu（bimb）Cl]（30）,[Cu（bimb）₃（CO₃）₂]_n（31）.X-ray diffraction structure analysis showed that their structure ranged from 0 D to 3 D frameworks.The diversity their structure may attribute to the different of coordination ability of inorganic anions.In chapter 6:The whole paper,especially the innovation points,were summarized by us,and a prospect of the future works was also made.
