Cd(Ⅱ)配位聚合物的合成及其对有毒阴离子的选择性识别
Synthesis of Cd(Ⅱ)coordination polymer and its selective recognition of toxic anions
摘要
Abstract
Using 5-(1-oxoisoindolin-2-yl)isophthalic acid(H2oia)and(1E,2E)-1,2-bis(1-(pyridin-4-yl)ethylidene)hydrazine(bpeh)as organic ligands,a novel coordination compound{[Cd(oia)(bpeh)0.5(NMP)(H2O)]}n was self-assembled with Cd2+at 100℃using the solvothermal method.The structure and properties of this compound were characterized through single crystal X-ray diffraction,powder X-ray diffraction,thermogravimetry,SEM,EDS and solid-state fluorescence analysis.Results revealed that the complex constitutes a 1D ladder chain structure formed by the deprotonated oia2-and the N-containing ligand bpeh that are connected to the seven-coordinated Cd2+centers.Furthermore,selective fluorescence experiments demonstrated that this coordination compound can simultaneously detect MnO4-and Cr2O7-anions in aqueous environments.关键词
