We present a detailed study of the photophysical properties of a tetraphenoxy‐substituted perylene bisimide derivative. The probe molecules were immobilized in a Shpol'skii matrix of hexadecane and investigated by single‐molecule spectroscopy at cryogenic temperatures. By using single‐molecule spectroscopic techniques we reveal the triplet substate kinetics and the fluorescence quantum yield, and we provide an estimate for the S 1 –S 0 transition dipole moment.
