摘　　要：通过缩合反应合成了2-羟基-1-萘甲醛缩4,4′-二氨基二苯醚希夫碱,使用红外光谱仪、核磁共振仪、元素分析仪对其结构进行了表征,并对其与金属离子如Ni^(2+)、Pb^(2+)、Cu^(2+)、Ce^(3+)、Ag^(+)、Zn^(2+)等作用时的荧光性质进行了研究。结果表明,不同金属离子对该希夫碱的荧光发射波长影响不大,但使其荧光强度发生了不同程度的改变,其中Pb^(2+)使其荧光强度增强最为显著。A new Schiff base was synthesized by condensation reaction of 4,4′-diaminodiphenyl ether reacting wit 2-hydroxy-1-naphthalaldehyde.The structure was characterized by fourier infrared spectrometer,nuclear magnetic resonance spectrometer and elemental analyzer.Fluorescent property about the title compound complexed with different metal ions such as Ni^(2+)、Pb^(2+)、Cu^(2+)、Ce^(3+)、Ag^(+)、Zn^(2+)was investigated.Fluorescence test results showed that the addition of metal ions had little effect on the fluorescence emission wavelength of the title compound,but the fluorescence intensity changed in different degrees.The fluorescence intensity of the title compound was enhanced by Pb^(2+).
