An excited-state intramolecular proton transfer (ESIPT) mechanism based two reactive probes HBTCo and HBTCu is reported for the selective detection of Co²⁺ and Cu⁺ respectively in a reducing aqueous environment. Co²⁺ and Cu⁺ mediated oxidative benzylic ether (C–O) bond cleavage offers ratiometric detection of these metal ions.
