Cover Story: Time-gated laser-spectroscopy enables the recording of delayed fluorescence, with lifetimes up to hundreds of microseconds, in diluted and aerated solutions of heavy-atom-free BODIPY fluorophores. Moreover, red-shifted room temperature phosphorescence is also detected in halogenated solvents or mediated by substituent-induced intramolecular charge transfer. Accurate excited-state calculations indicate that the intersystem crossing and the reverse process are thermodynamically feasible between the almost isoenergetic relaxed S1 and T2 states. These channels rule the thermally activated delayed emission and phosphorescence probability. These findings entail a breakthrough in the “classic” interpretation of the photophysical properties of the renowned BODIPY and its derivatives. View this paper
