Fluorescence switching by O-dearylation of 7-aryloxycoumarins. Development of novel fluorescence probes to detect reactive oxygen species with high selectivity

Coumarins exhibit fluorescence that is dependent on the nature of their substituents. We have found that the strong fluorescence of 7-hydroxycoumarin in aqueous media is completely lost in 7-aryloxycoumarins. Judging from the relation between the electron
