Recently we started to develop a new class of dyes based upon the glycoconjugation of disperse dyes with mono- or disaccharides. We used the term “naturalised” to describe these dyes because we used natural lactose in the glycoconjugation process, and also because they are similar to real natural dyes, the hydrosolubility of which is based upon the saccharidic moiety attached to the chromophore, as
最近,我们开始开发一类基于分散染料与单糖或二糖的糖共轭的新型染料。我们使用术语“天然化”来描述这些染料,因为我们在糖缀合过程中使用了天然乳糖,还因为它们类似于真正的天然染料,其水溶性基于附着在发色团上的糖基部分,如胭脂虫红酸或红花素。提交归化过程的合成染料由小的发色团分子组成,主要是偶氮,而当通过二价间隔物添加单个乳糖分子时,具有较高质量的较大染料分子在水中没有明显的溶解度,这与较小的染料。为了克服这个困难,在本文中,我们提出了通过双糖缀合过程插入两个乳糖单元的第一种方法。这里介绍的程序允许成功插入一个间隔物,丙二酸,它可以与两个乳糖单元连接,以便即使是大染料也能溶解。(© Wiley-VCH Verlag GmbH & Co.
