摘　　要：以4-溴-1,8-萘酐和4-硝基-1,8-萘酐为原料制备了分别含碳-碳双键和硅氧烷结构的可聚合萘酰亚胺衍生物4-二甲胺基-1,8-萘酐、4-二甲胺基-N-烯丙基-1,8-萘酰亚胺、4-硝基-N-烯丙基-1,8-萘酰亚胺和4-硝基-N-[(3-三甲氧基硅基)丙基]-1,8-萘酰亚胺.通过1H、13C及多种二维核磁共振(NMR)技术表征了其分子结构,完成了氢和碳的谱峰归属.利用紫外吸收光谱与荧光发射光谱研究了这些化合物的光学性质,并讨论了取代基对这些化合物荧光性质的影响.Polymerizable 1, 8-naphthalimides derivatives, 4-dimethylamino-N-allyl-1, 8-naphthalic anhydride, 4 nitro-N-allyl-1, 8-naphthalic anhydride and 4-nitro-N-[-（3-trim-ethoxysilane）-propyl3-1, 8-naphthalic anhydride, all containing polymerizable carbon- carbon double bond or 3-trimethoxysilane groups, were synthesized from 4-bromine-1, 8-naphthalic anhydride and 4-nitro-1, 8-naphthalic anhydride. The structure of these compounds were determined by 1D（^1H and ^13C NMR） and 2D NMR techniques, including ^1H-^1H COSY. HMBC and HSQC. The ^1H and ^13C NMR chemical shifts of the compounds were assigned. The photo-physical properties of the compounds were studied by ultraviolet absorption spectroscopy and fluorescence emission spectroscopy. The sub-stituent effects on the fluorescence intensities of the compounds were discussed.
