Abstract
A turn-on fluorescent probe was designed for selective cyanide anion sensing in aqueous and biological environments. The probe underwent an intramolecular crossed-benzoin reaction in the presence of KCN to expel the fluorophore resorufin. This probe was sensitive to KCN concentrations as low as 4 nM in aqueous media.
摘要
设计了一种开启型荧光探针，用于在水性和生物环境中选择性检测氰根阴离子。在氰化钾存在下，该探针发生分子内交叉安息香反应，释放出荧光团试卤灵。此探针在水性介质中对低至4 nM的氰化钾浓度敏感。
