Highly Selective Excited State Intramolecular Proton Transfer (ESIPT)-Based Superoxide Probing

Highly Selective Excited State Intramolecular Proton Transfer (ESIPT)-Based Superoxide Probing

Two novel fluorescent probe conjugates of 2-(benzothiazol-2-yl)-phenol (HBT) enable ratiometric and selective superoxide detection by an established excited state intramolecular proton transfer (ESIPT) mechanism giving a 60-fold intensity increase.
