摘  要:
利用8-羟基喹啉衍生物和4-肼基-N-(2-乙基己烷)-1,8-萘酰亚胺反应,合成了3个新颖的含有8-羟基喹啉单元的席夫碱化合物,3个化合物分子结构分别通过红外光谱、核磁共振谱,高分辨质谱的表征。相应光物理性能分别利用吸收光谱法和荧光光谱法进行了研究。结果显示,3个含有8-羟基喹啉单元的席夫碱化合物在440~460nm范围内各有一个很强的吸收峰,荧光发射峰出现在500~550nm范围内,相应的紫外可见吸收和荧光发射峰随着共轭体系的增加都发生了红移。随着溶剂极性的增加,各化合物的发射峰也出现红移现象,这是因为Stoke’s位移与溶剂的极性成正比,说明该类分子产生的荧光是由π-π*跃迁造成的。

摘  要:
In this paper,we synthesized three new Schiff bases containing 8-hydroxy quinoline unit by the combination of 8-hydroxy quinoline derivatives and 4-Hydrazine-N-(2-ethylhexyl)-1,8-Naphthalimide.Their structures were characterized by IR,NMR and HRMS spectra.The corresponding photophysical properties were studied by UV-visible and fluorescence spectra.The results show that a strong absorption was observed around 440~460nm and the emission around 500~550nm for each of Schiff bases with 8-hydroxy quinoline unit.Not only the corresponding absorption and emission were found red shift along with the increase of the conjugation,but also the emission of each compound appears red shift with the increase of polarity of solvents.This is because a polar solvent is proportional to the Stoke's shift,which means that the emission of the moleculars are caused byπ-π*transitions.
