Synthesis, Luminescent Sensing And Catalysis Properties Of Coordination Polymers With Thiazole Or Imino Group Sites

In recent years, functional metal-organic frameworks (MOFs) is one of the mostrapidly developing areas of chemical science, not only because of exceptionallyartistic architectures of this materials, but also because of their justifiably enormouspotential for many practical applications such as gas adsorption and separation,catalysis and luminescence. These excellent properties and extensive applications aremostly attributed to the distinct structure and composition of this material. Over avery large number of previous studies, the facts evidence that the success ofsynthesizing functional MOFs will rely on a systematic development of suitablesecondary building units (SBUs) in which structurally and functionally diverse classof novel materials might evolve. Organic carboxylate ligands have been widely usedin synthesizing porous MOFs or magnetic materials with esthetical topologies andunique properties because of the controllable length of ligand, the variouscoordination modes of the carboxyl group and functionalized site on the ligand,which can ornament the pore surfaces. The special features or unique sites of organicligands in the structure determine the chemical environment and function of theresulting void spaces of this material. In this thesis, we used two ligand constructseveral metal-organic coordination polymers and introduced their structures andproperties. This thesis is divided into four chapters.In the first chapter, we introduced the development situation of functionalmetal-organic frameworks and the hot applications of functional MOFs in variousfields. Moreover, it is indicated that the significance and the research progress of ourselected topic.In the second chapter, two metal-organic frameworks, Zn(btdb)(DMA)·H2O (1)and Co(btdb)(DMA)·H2O (2) have been successfully constructed by4,4’-(benzothiadiazole-4,7-diyl)dibenzoate (H2btdb). These complexes areisomorphism, exhibiting a interdigitating three-dimensional (2D+2Dâ†'3D) porousstructure. The influence of Cd2+on the luminescent feature of complex1also was studied and discussed.In the third chapter, two series of lanthanide–organic frameworks with theformula [Ln(BTATB)(DMF)2(H2O)]·DMF·2H2O (Ln=La(3), Eu(4), Tb(5), Er(6))and [Ln(BTATB)(H2O)2]·2DMA·4H2O (Ln=Er(7), Yb(8), Lu(9)), respectively, havebeen solvothermally synthesized from4,4’,4’’-(benzene-1,3,5-triyltris(azanediyl))tribenzoate (H3BTATB) and Ln(NO3)3under DMF or DMA media. Series A featuresan interesting2D interdigitated layer architecture with (6,3) topology while series Bexhibits2D bilayer structure. The luminescent and catalytic properties of thesecomplexes also were studied and introduced in this chapter.In the conclusion, the structures and functional properties of the tenmetal-organic coordination polymers have been summarized. The contributions offunctional organic ligand with functional sites to construction of the functionalmetal-organic coordination polymers have been discussed. The research provided anew route for the construction and design of metal-organic coordination polymers.
