A novel “turn-on” fluorescent probe for high selectivity, rapid detection and imaging of HOCl based on the protection of carbaldehyde with 2-mercaptoethanol.
Herein, a new near-infrared turn-on fluorescent probe, YPT, was designed and synthesized for the rapid detection of Zn2+, which exhibited low limit of detection for Zn2+ (12 nM) as well as a favorable large Stokes shift (λem − λex = 168 nm).
