Abstract
- A novel cyclic chalcone fluorescent probe C-PN was synthesized to detect ONOO <superscript>-</superscript> . After reaction with peroxynitrite, the double bond of C-PN in the cyclic chalcone structure was disconnected, which caused the change of intramolecular charge transfer (ICT) effect, emitting blue fluorescence and quenching orange red fluorescence. Visible to the naked eye, the color of the probe solution changed. The probe showed low sensitivity (detection limit = 20.2 nm), short response time (less than 60 s) at low concentration of ONOO <superscript>-</superscript> , good visibility, and good selectivity and stability for ONOO <superscript>-</superscript> .<br /> (© 2024.
