摘要：

The stimulated-emission-pumping (SEP) technique has been applied to the dually fluorescent "double" benzoxazoles. The time evolution of both the primary and phototautomeric fluorescences and the time-resolved spectra with and without dump pulses have been measured. The reversibility of excited-state proton-transfer reactions for "double" benzoxazoles is entirely confirmed.
