摘　　要：以4-溴-1,8-萘二甲酸酐为原料,与端基含有氨基的伯胺(如苯胺)和自制1.0GPAMAM发生酰胺化反应得到4-溴-1,8-萘酰亚胺,将其C4-位的溴被甲氧基和乙氧基取代进而得到4种具有强烈荧光性能的萘酰亚胺类荧光增白剂。经FT-IR表征其结构,用UV-vis、荧光光谱等手段研究了它们在水溶液中光物理化学性质。结果表明:含有大分子PAMAM结构的增白剂荧光性能较好,增白能力较强,且水溶性良好,荧光猝灭浓度为2×10-3 mg/mL,具有很好的实用价值。Four naphthalimide fluorescent brighteners was synthesized from 4-bromo 1,8 naphthalic anhydride and the amino terminal group with primary amines such as aniline and 1.0G PAMAM via amidation reaction and substitution by metnoxy and ethoxy. The structure was characterized by FTIR, Ultraviolet-visible absorption and fluorescence spectra of the target product were investigated. The results showed that： with the structure of macromolecular PAMAM, the performance of FBs was improved. Such as whitening ability and water solubility. The fluorescence quenching concentration was 2 ×10-3 mg / mL.
