We reported a new approach to achieve enhanced selectivity with a drastic turn-on fluorescence response for the detection of Cys through dual intramolecular cyclization processes and dual PET and ICT quenching mechanisms by the incorporation of an acrylate and a maleimide group onto two opposite sides of a single coumarin fluorophore.
我们报道了一种新方法，通过在单个香豆素荧光团的两个相对侧引入丙烯酸酯和马来酰亚胺基团，利用双分子内环化过程以及双正电子转移（PET）和分子内电荷转移（ICT）猝灭机制，实现对胱氨酸（Cys）检测的增强选择性和强烈的荧光开启响应。
