Characterization of the photophysical parameters for three perylene bisimide derivatives is presented. We exploited time‐resolved and steady‐state spectroscopy on both ensembles and single molecules under ambient as well as cryogenic (1.4 K) conditions. The finding is that these chromophores show extraordinary high fluorescence‐emission rates, low intersystem crossing yields to the triplet state, and relatively short triplet lifetimes.
