摘　　要：以4-硝基邻苯二甲酰亚胺为原料制备了3支N-苄基邻苯二甲酰亚胺分散染料,并采用傅里叶变换红外光谱、核磁共振氛谱和质谱分析对合成的中间体和染料进行表征。结果表明:对N-苄基邻苯二甲酰亚胺基团苯环进行溴基取代或氰基取代后,可分别对染料产生浅色效应和深色效应。相较于三氯甲烷和甲苯,所制备染料色光在介电常数较大的丙酮、N,N-二甲基甲酰胺和乙醇溶剂中产生红移。Three N-benzyl substituted phthalimide azo disperse dyes were synthesized by 4-Nitrophthalimide and characterized by Fourier transform infrared spectroscopy, ~H-nuclear magnetic resonance and mass spectrometry. The results showed that bromo and cyano substitution on the N-benzyl phthalimide ring resulted in hypsochromic and bathochromic shifts of the absorption maxima respectively. Compared with trichloro-methane and toluene, dyes in the larger dielectric constant of acetone, N, N-dimethylformamide and ethanol solvent caused bathochromic shifts.
