Coordination Polymers Based On Benzotriazol-5-carboxylic Acid And Biphenyl Type Linear Dicarboxylic Acid

In this paper, we use different carboxylic acid compound as organic ligands,select different metal salts as metalions to synthesize coordination polymers by usingsolvent hot method. We determination the three new synthesized coordinationpolymers by infrared spectrum (IR), X-ray single crystal diffraction analysis (X-ray),X-ray powder diffraction analysis (P-XRD), and thermogravimetric analysis (TGA)methods, has carried on the proof and judgement to the three kinds of coordinationpolymers.We also explore fluorescent or magnetic and other special properties ofsome complexes separately.There are four parts in this paper:In the first chapter, the coordination chemistry and coordination polymer areintroduced simply, and mainly introduce the recent research situation of thecoordination polymers that based on the structure of organic carboxylic acid ligandsand the ligands that used in this paper. At the end of this chapter, the significance ofthe selected topic is interpreted.In the second chapter, we introduce the new coordination polymer1[Ni3(btca)2(μ3-OH)(EtO)(H2O)2·DMF] which has three dimensional hole structure,with benzotriazol-5-carboxylic acid as organic ligands, metal nickel as metal center.In the third chapter,we use1,5-Dibromo-2,4-dimethylbenzene and4-Methoxy-carbonylphenylboronic acid to synthesize a carboxylic acid type of ligandp-terphenyl-4,4″-dicarboxylic acid,2′,5′-dimethyl by Suzuki coupling reaction. Thensynthesis two new different two-dimensional laminar complexes2[Cu(L)(H2O)·1.5H2O] and3[Cd(L)(DMF)(H2O)·DMF·2H2O] with this ligand asorganic ligands, CuCl2and Cd(NO3)3as metal salt. Then the properties of them arestudied.The fourth chapter is the conclusion of this paper, the three coordinationpolymers that new synthesized are summarized.
