The excited state dynamics of rubrene in solution and in the single crystal were studied by femtosecond pump–probe spectroscopy under various excitation conditions. Singlet fission was demonstrated to play a predominant role in the excited state relaxation of the rubrene crystal in contrast to rubre...
