Description
Summary:A highly selective fluorogenic signaling fluoride-sensor through an excited-state intermolecular proton transfer (ESPT) signaling transduction mechanism was obtained and structurally characterized. A highly selective fluorogenic signaling fluoride-sensor Ru- HL, comprised of Ru-bipy moiety (bipy = 2,2′-bipyridine) and 3-hydroxyl-2-naphthoylhydrazine was prepared and structurally characterized. The fluorescence spectra titration revealed the high selectivity and sensitivity of Ru- HL for F − through an excited-state intermolecular proton transfer (ESPT) signaling transduction mechanism.
