The optoelectronic properties of single‐crystal rubrene are investigated by microwave and optical spectroscopy, demonstrating the anisotropy, ambipolarity, and dynamics of the charge carriers. They are discussed in terms of charge recombination, exciton‐exciton annihilation, quantum efficiency, triplet contribution, the extinction coefficient of radical cations/anions, and density functional theory.
