- Abstract
Drawing upon an intramolecular cyclization/annulation reaction sequence mediated by Hg2+ ions, a BODIPY‐based fluorescent probe decorated with an alkynyl hydrazone motif responds rapidly and selectively to Hg2+ ions, with a detection limit of 29 nM and a fluorescence turn‐on ratio of 15‐fold. With the addition of Hg2+ ions, the BODIPY‐based alkynyl hydrazone transforms into a pyrazole ring to mediate a turn‐on emission response clearly observable to the naked eye under visible light excitation.
