几种荧光Schiff碱试剂的合成与表征
摘要：本文用β-萘胺和萘乙二胺盐酸盐等和对甲氧基苯甲醛、香兰素等在乙醇或DMF溶剂中进行反应，合成几种新的Schiff碱，并用元素分析、紫外-可见光谱、荧光发射光谱、氢核磁共振谱和碳核磁共振谱等方法对合成的Schiff碱进行了表征。由于C=N双键的生成，使得Schiff碱比原料的共轭链加长，有望成为新的荧光试剂。

Synthesis and characterization of fluorescent Schiff bases
Abstract: Several new Schiff bases were synthesized using β-naphthylamine and 2-(1-Naphthylamino)ethylamine dihydrochloride with p-methoxybenzaldehyde、vanillin in ethanol or DMF. The products were characterized by UV-vis spectra, fluorescence spectra, 1H NMR and 13C NMR and so on. As the formation of C=N double bond, the conjugated chains of Schiff bases are longer than the stuffs，which are expected to become new fluorescent reagents.
Keywords: fluorescence, Schiff base, 2-(1-Naphthylamino)ethylamine dihydrochloride, p-methoxybenzaldehyde, β-naphthylamine
