We report the development of a two-component probe system as fluorescence turn-on assay of simple saccharides. The quenching of an anionic conjugated water-soluble polymer by a cationic quencher has been reported previously. Three different boronic acid functionalized benzyl viologens and three conjugated polymers of the poly(aryleneethynylene) type form nine non-fluorescent complexes. This small library discriminates nine different simple saccharides in aqueous solutions by fluorescence turn-on in a displacement assay. The saccharides can be discriminated and identified with this simple system.
我们报道了一种双组分探针系统的开发，用于简单糖类的荧光开启检测。此前已有报道称，阳离子猝灭剂可使阴离子共轭水溶性聚合物发生猝灭。三种不同的硼酸官能化苄基紫精和三种聚亚芳基乙炔类型的共轭聚合物形成了九种非荧光复合物。这个小型文库通过置换检测中的荧光开启，在水溶液中区分九种不同的简单糖类。利用这个简单的系统可以区分和识别这些糖类。
