Abstract
Cyanine dyes with indolium-coumarin linkages exhibit selective fluorescence enhancement for cyanide anions (CN(-)) via the nucleophilic interaction of CN(-) with their indolium carbon atoms. This facilitates rapid (detection time: 1 min) and sensitive (detection limit: 0.4 μM) sensing of CN(-) in aqueous media.
摘要
具有吲哚鎓-香豆素连接基团的菁染料通过氰根阴离子（CN⁻）与它们的吲哚鎓碳原子之间的亲核相互作用，对氰根阴离子（CN⁻）表现出选择性荧光增强。这有助于在水性介质中快速（检测时间：1分钟）且灵敏（检测限：0.4 μM）地检测CN⁻。
