摘　　要：为研究荧光染料结构与性能之间的关系,以4-溴-1,8-萘二甲酸酐和含不同取代基的邻苯二胺为原料,合成了3种1,8-萘酰亚胺类荧光染料,并对其结构进行表征,同时测定其紫外-可见光漫反射光谱、紫外-可见光吸收光谱及单光子荧光光谱。在基态优化构型基础上,采用时间依赖密度泛函理论计算该类分散染料在二氯甲烷溶剂中的紫外-可见光吸收光谱的吸收波长和单光子荧光光谱的发射波长。实验测试和理论计算结果均表明,随着邻苯二胺上取代基(—H,—CH_3,—OCH_3)供电子能力的增强,染料吸收光谱发生红移的同时荧光强度会减弱。将3种染料应用于涤纶织物染色,对染色织物的荧光性能和色牢度进行比较测试,结果表明染料b的染色性能最佳。In order to study the relationship between dye chemical structure and its properties,three naphthalimide-based fluorescent dyes were synthesized from 4-bromo-1,8-naphthalic anhydride and different substituted o-phenylenediamine. The structures were characterized,and the UV-Vis diffusion reflectance spectra,UV-Vis absorption spectra and single-photon fluorescent spectra were investigated.The UV-Vis absorption spectra and single-photon fluorescent emission spectra wavelengths based on the optimized structures were obtained by the time-dependent density function theory. The calculated results well agree with the experimental data,where bathochromic shifts of absorption spectra happens and fluorescent intensity decreases with the electron-donating capability（ —H,—CH_3,—OCH_3） of the substituents. The fluorescence and fastness properties of dyed polyester fabrics using these three dyes are also determined,and dye b has the best dyeing property.
