一种多孔三维超分子钴配合物的合成与光催化性能
Synthesis and Photocatalytic Property of a Porous Three-Dimensional Supramolecular Cobalt Compound
摘要
Abstract
A new porous cobalt compound [Co(L)1 .5 (BDC)(H 2 O)3 ]n (1 )(L=N,N′-bis(3-pyridyl) adipamide,H 2 BDC = 1,2-benzenedicarboxylic acid)was prepared by the self-assembly process of hydrothermal synthesis by selecting the mixed ligands of the flexible bis(pyridyl)-bis(amide)L and the aromatic dicarboxylate H 2 BDC.The crystal structure of the compound was characterized by the element analysis,IR and the single crystal X-ray diffraction technique.Experimental results show that the compound belongs to triclinic system,P 1 space group,a =1.09787 (10)nm,b =1.21382 (11)nm, c =1.42940(13)nm,α= 72.788 (2 )°,β= 75.235 (2 )°,γ= 72.127 (2 )°,V = 1.7033 (3 )nm3 , Mr =575.43,Z =2,D cal =1.122 g/cm3 ,μ=0.549 mm-1 ,F (000)=598,S =1.064,R 1 =0.0543,ωR 2 =0.1518.The metal cobalt ions are bridged by the bidentate L ligands to form a one-dimensional [Co(L)1 .5 ]2n+n chain structrue,and the carboxylate ligand BDC is suspended on both sides of this chain with a monodentated coordination mode.A three-dimensional supramolecular porous network with large pore structure is expanded by the hydrogen-bonding interactions among one-dimensional chains. This porous cobalt compound shows the remarkable photocatalytic degradation ability to the organic dye molecules methylene blue or congo red under the UV light.关键词
