A turn-on fluorescent probe for selective detection of peroxynitrite via electrophilic addition mechanism and cellular imaging

Abstract Peroxynitrite (ONOO-), a key pathological mediator, demands fast and reliable detection. Herein, we report TADBI, a turn-on fluorescent probe based on triphenylamine-benzo indole framework. TADBI shows a rapid (< 50 s) colorimetric change from violet to colourless, and a strong fluorescence...
