| 摘 要： | 本文以2-氨基-4-氯-5-醛基噻唑为重氮组分合成了一系列含醛基分散染料,进而与合活泼亚甲基的化合物缩合得到一系列含氰乙烯基的分散染料.对染料结构进行了表征,并测试了染料的吸收光谱.结果表明氰乙烯基的引入使得λmax和εmax都有所增大.

| Abstract: | A series of disperse dyes containing a formyl group were synthesized from diazonium salts of 2-amino-4-chloro-5-formylthiazole,then a series of disperse dyes containing a cyanovinyl were obtained by condensation of active methylene compounds with these dyes.The structures of dyes were characterized and absorption spectra of dyes were measured.The results showed that λmax and εmax were increased when a cyanovinyl connected in a dye. |
