Disazo dyes were derived from heterocyclic amines by diazotizing 2-Amino-6-nitrobenzothiazole, 2-Amino-5-nitrothiazole, and 2-Amino-3,5-dinitrothiophene and coupling with Aniline as middle components, and 1-Naphthylamine, N,N-Dimethyl-1-naphthylamine, N,N-Dibutylaniline and N,N-Diethylaniline, Aniline as final components. Disazo red, violet, blue dyes were synthesized and the absorption bands of these
双偶氮染料衍生自杂环胺,通过重氮化 2-氨基-6-硝基苯并噻唑、2-氨基-5-硝基噻唑和 2-氨基-3,5-二硝基噻吩并与作为中间组分的苯胺偶联,以及 1-萘胺、N、 N-二甲基-1-萘胺、N,N-二丁基苯胺和N,N-二乙基苯胺、苯胺作为最终组分。合成了双偶氮红、紫、蓝染料,并在 512-668 nm 范围内观察到这些化合物的吸收带。还讨论了重氮组分和最终偶联组分对染料可见光吸收最大值的影响。
