2-乙氧基苯甲醛缩4-氨基安替比林席夫碱的合成及其荧光性质研究

Synthesis and Fluorescence Properties of 2-ethoxy Benzaldehyde 4-amino Antipyrylin Schiff Base

通过加成-消除反应合成了2-乙氧基苯甲醛缩4-氨基安替比林席夫碱,通过IR、1H-NMR和元素分析对其结构进行了表征.并对其与Zn^(2+)、Cu^(2+)、Co^(2+)、Ni^(2+)、La^(3+)、Ce^(3+)、Sr^(2+)、Pb^(2+)、Cd^(2+)、Ru^(3+)、Ag^(+)等金属离子作用前后的荧光性质进行了研究.实验结果表明,金属离子的加入对2-乙氧基苯甲醛缩4-氨基安替比林席夫碱的荧光发射波长影响不大,但荧光强度发生了不同程度的改变.其中Cu^(2+)与席夫碱络合后的荧光强度增强显著.

2-ethoxy benzaldehyde 4-amino antipyrylin Schiff base has been synthesized by addition-elimination reaction.Its structure was characterized by IR,1H-NMR and elemental analyzer.The fluorescence property was studied before and after interacting with different metal ions such as Zn^(2+),Cu^(2+),Co^(2+),Ni^(2+),La^(3+),Ce^(3+),Sr^(2+),Pb^(2+),Cd^(2+),Ru^(3+),Ag^(+),etc.The test result showed that the addition of metal ion had little effect on the emission wavelength of Schiff base ligand,but the fluorescence intensity changed in different degree.The fluorescence intensity of Cu^(2+)complexed with Schiff base was increased significantly.
