The kinetics of previously reported excited-state intramolecular proton transfer (ESIPT) reactions were investigated using single-photon counting techniques of high temporal resolution: 2,5-bis-( benzoxazolyl)-hydroquinone undergoing single PT emits two fluorescence bands, the primary (450 nm) and t
Picosecond kinetics of excited-state single-or double-proton transfer along intramolecular hydrogen bonds were analyzed for three molecules: 2,5-his-( 2-benzoxazolyl )hydroquinone, its monomethoxy-derivative and 3,6-bis-(bbenzoxazolyl)pyrocatechol. Forward and back proton-transfer rate constants wer
