Abstract

Tetraphenylethylene is a prototypical example of a molecule displaying aggregation-induced emission. Despite many studies on the optical properties of TPE and its derivatives, the origin of the non-emissive behavior in the gas phase or in dilute solutions has yet to be unravelled. Here, we identify the ultrafast deactivation mechanisms responsible for the fluoresence quenching in isolated TPE.
