Zn(Ⅱ)配合物的合成及其对金霉素的荧光传感
Synthesis of Zn(Ⅱ)complex and its fluorescence sensing for chlortetracycline
摘要
Abstract
This study selected solvothermal method to prepare a zinc complex{[Zn(NDA)(1,2-DPE)0.5(H2O)]·0.5H2O}n(1)with a mixed organic ligand containing conjugated structure of 2,7-naphthal-enedicarboxylic acid and(E)-1,2-di(pyridin-4-yl)ethylene and Zn2+.The structure and properties of complex 1 were characterized by X-ray single crystal diffraction,infrared spectroscopy,thermogravi-metric analysis,etc.,and its fluorescence detection ability for streptomycin was analyzed in depth.The analysis results of X-ray single crystal diffraction reveal that it crystallizes in the P21/c space group of the monoclinic crystal system.Research has shown that complex 1,due to its excellent fluorescence properties and stability,can be used for selective detection of streptomycin.The fitting results show that Ksv=1.784 4×104 L/mol.Furthermore,further exploration of its fluorescence quenching mecha-nism suggests that the occurrence of fluorescence quenching may be due to energy competition absorp-tion between chloramphenicol and complex 1.关键词
