中文摘要：

以1,4,5,8-萘四甲酸二酐（1）和2-乙基己胺（2）为原料,设计并合成了3种新型的1,4,5,8-萘酰亚胺类衍生物,其结构经1H NMR,IR和MS表征。中间体N-（2-乙基己基）-萘-1,8-二甲酸单酐-4,5-单甲酰亚胺的最佳反应条件为：19.7 mmol,n（1）∶n（2）=1.1∶1.0,以醋酸锌为催化剂,在DMF（20 mL）中于140℃反应15h,收率25%。

英文摘要：

Three novel 1,4,5,8-naphthalimide derivatives were designed and synthesized from 1,4,5,8-naphthalenetetracarboxylic dianhydride（1） and 2-ethylhexan-1-amine（2）.The structures were characterized by 1H NMR,IR and MS.The optimum reaction conditions of synthesizing intermediate N-（2-ethylhexyl）-1,4,5,8-naphthalenetetracarboxylic-1,8-anhydride-4,5-imide were as follows： 1 was 9.7 mmol;n（1） ∶n（2） was 1.1 ∶1.0;Zinc acetate was used as the catalyst and the reaction carried out in DMF（20 mL） at 140 ℃ for 15 h.The yield was 25% under the optimum reaction conditions.
