[Abstract]:The coordination compounds of metal polycarboxylic ligands are novel and unique, and then the potential applications of it are widely used, such as adsorption, magnetism, fluorescence, electrochemistry, catalysis, etc. Besides, the coordination of polycarboxylic ligands is more diverse and more complex than other ligands, and is easy to be assembled. A new unique structure and specific functional coordination compounds. Therefore, the research on the design, synthesis and properties of this kind of complexes has long been concerned by researchers. Polyoxometalate is an excellent inorganic metal oxygen cluster in a comprehensive way. There are many accidents when the complexes are combined with organic ligands to form complexes. In recent years, the design and synthesis of metal organic coordination polymers have been designed and synthesized with the general application of the synthetic methods of polymer (ionic calorimetry, hydrothermal method and solvent heat etc.). By taking Zn (II) as the central ion, 2,4- two benzoyl benzoyl two formic acid and 2,5- two benzoyl terephthalic terephthalic acid as the main ligands, this paper has designed and synthesized 2 unique metal organic coordination polymers in different reaction conditions. The crystal structure analysis, elemental analysis, IR characterization and TGA analysis were carried out and the fluorescence was studied. The results are as follows: 1, 2,4- two benzoyl benzene two formic acid (H_2L~1), 2,5- two benzoyl terephthalic acid (H2L2) as the main ligand, 1,3- double (1,2,4- three azole -1- methyl) benzene as the auxiliary ligand (1,3-bis, 1,3-bis) as the auxiliary ligand (1,3-bis) as the auxiliary ligand (1,3-bis) as the auxiliary ligand (1,3-bis, 1,3-bis) as the auxiliary ligand (1,3-bis). (1,2,4-triazol-1-ylmethyl) benzene), with the transition metal Zn (II) constructed in the hydrothermal condition, the complex 1.[Zn_2L~1L~2 (mbtz)]. H_2O (1) complex 1, the four carboxyl groups formed a pulley like [Zn2 (CO2) 4] building unit through the double tooth distribution bridge and two adjacent Zn (II), and the ligands connected two adjacent building units. 1D chain structure is constructed. Ligand L2 connects adjacent 1D chains to form a layered structure of 2D, and linear nitrogen ligand mbtz extends the two-dimensional layer to 3D with 6 connected PCU topological structure.2, with 2,4- two benzoyl benzoyl benzoic acid (H_2L~1), 2,5- two benzoyl terephthalic terephthalic acid (H2L2) and new nitrogen ligand. Three azole) propane is an auxiliary ligand, (1,3-bis (1,2,4-triazol-1-yl) propane). By altering the reaction conditions and the transition metal Zn (II), the complex 2.[Zn_4L_2~1L_2~2 (BTP) _2]. 7H_2O (2) complex is constructed very similar to the structure of the complex 2 and 1, and the dual nucleus [Zn2 (CO2) 4]SBU is the 6 connection point. A three-dimensional PCU topology.3 is formed, with 2,5- two benzoyl terephthalic acid (H2L2) as the main ligand and 3.[Dy (L2) 1.5 (H2O) 2] 2H2O] (3) complex with rare earth metal Dy (III) under hydrothermal conditions. In 3, the dual core [Dy2O4 (CO2) building unit is a node, and a three-dimensional topological structure is constructed by the ligands, with a topological symbol of 412. 63 The thermal stability and fluorescence properties of compound 3 were studied by.4, with Wells-Dawson type phosphotungstate as the main ligand, adjacent phenanthroline (phen) as the auxiliary ligand and transition metal CuII and synthesis of compound 4, [Cu (phen) 2 (H2O)]2+ cations and [Cu2 (phen) 3 (H2O) 3 (P2W18O62) anion through the pion - pi In the 1D chain, the adjacent 1D chain was extended to 3D supramolecular structure through the intermolecular force of O-H. O. In addition, we also studied the photocatalytic properties of compound 4,.[Cu2 (phen) 3 (H2O) 3 (P2W18O62)][Cu (phen) 2 (H2O)].
