摘　　要：合成制备了四种1,8-萘酰亚胺类衍生物,制备纤维素荧光水凝胶。采用核磁共振(NMR)技术对合成的1,8-萘酰亚胺类衍生物进行结构确认。利用荧光发射光谱和激发谱对不同荧光分子浓度纤维素荧光水凝胶的荧光光谱进行分析,根据荧光强度与荧光出峰位置探讨了荧光分子在纤维素水凝胶中的聚集态结构及运动行为。随1,8-萘酰亚胺类衍生物浓度增加,分子凝聚对复合水凝胶的荧光行为影响极大。Four 1,8 - naphthalimide derivatives were synthesized. A series of complex hydrogel of 1,8 -naphthalimide derivatives/cellulose with different concentration of 1,8 - naphthalimide derivatives were prepared. The structure of 1,8 - naphthalimide derivatives were characterized by NMR. The fluorescence of 1,8 -pared. The structure of 1,8 - naphthalimide derivatives were characterized by NMR. The fluorescence ol 1,8 - naphthalimide derivatives/cellulose complex hydrogel were studied by fluorescence emission spectra and exci- tation spectra. With the increased concentration of 1,8 - naphthalimide derivatives, the fluorescence perform- ance of complex hydrogel was influenced greatly by molecular aggregation.
