摘　　要：合成了4-(二乙氨基)水杨醛缩4-氨基安替比林席夫碱,通过红外光谱、核磁共振谱、元素分析等对其结构进行了表征。利用分子荧光仪对其与Zn^(2+)、Ni^(2+)、Co^(2+)、Pb^(2+)、Cd^(2+)、La^(3+)、Ce^(3+)、Sr^(2+)、Ag^(+)、Ru^(3+)等金属离子作用前后的荧光性质进行了检测。检测结果表明,加入不同的金属离子后,该希夫碱的荧光发射波长略有变化,但荧光强度发生了不同程度的改变,其中Ru^(3+)与希夫碱作用后的荧光强度显著增强。A new Schiff base was synthesized by 4-(diethylamino)salicylaldehyed reacting with 4-amino-antipyrylin.Its structure was characterized by Fourier infrared spectrometer,nuclear magnetic resonance spectrometer and elemental analyzer.The fluorescence properties of the compounds were studied by molecular fluorimeter while before and after interacting with metal ions such as Zn^(2+),Ni^(2+),Co^(2+),Pb^(2+),Cd^(2+),La^(3+),Ce^(3+),Sr^(2+),Ag^(+),Ru^(3+),etc.The fluorescence test results show that the addition of metal ions has little effect on the fluorescence emission wavelength of Schiff base,but the fluorescence intensity changes in different degree.The fluorescence intensity of Schiff base when complexed with Ruthenium ion is increased significantly.
