Synthesis, Structure And Property Investigations Of Coordination Polymers Constructed With H₃BTB And Sulfate Ligands

In this thesis, we prepared five metal organic frameworks（MOFs） with different structure and dimensionality by using ligands H₃BTB（ 1,3,5-tris（4-carboxyphenyl）benezene）or sulfate, metal salts and auxiliary ligands in the solvent thermal condition. The structures and properties of the complexes were characterized by X-ray single crystal diffraction, the powder X-ray diffraction, element analysis, IR spectroscopy, fluorescent emission spectrum,gas adsorption and thermogravimetric analysis. The main sections are as follows:Chapter 1: IntroductionResearch progress, synthetic methods, classification and applications of MOFs materials were introduced, and research purpose and significance of this thesis were presented.Chapter 2: Synthesis, structure and property investigation of metal organic frameworks with H3 BTB ligand.The tricarboxlic ligands H3 BTB were synthesized by 4’-methylacetophenone and ethanol.We prepared four MOF materials by the reaction of different metal ions with H3 BTB in the condition of solvent thermal reaction, and investigated their structures and properties.Chapter 3: Synthesis, structure and property investigation of sulfate coordination polymerA new sulfate coordination polymers was prepared by using organic amine as a template in the condition of solvent thermal reaction, and its structure was characterized by TGA,PXRD and single-crystal X-ray diffraction.
