文摘

A dihydroxy perylenequinonoid dye (DHPQ) is exploited as an effective probe for hydrogen persulfide detection. DHPQ is found to be reversible fluorescent probe due to the excited state intramolecular hydrogen transfer process. DHPQ exhibits a highly sensitive turn-on fluorescence (600-fold enhanced response) and low detection limit (18.2 nM). The reversible detection method has been successfully used in both solvents and living HeLa cells.
