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.
