Abstract

Very short fluorescence lifetimes evidence ultrafast deactivation of photoexcited molecules. To unveil the underlying mechanism for two compounds exhibiting (sub)picosecond emission dynamics, we combine femtosecond fluorescence upconversion with high pressure liquid-phase spectroscopy. For the triazene berenil, the absence of a pressure dependence corroborates a bicycle-pedal motion as ...
