Experimentally determined quantum yields, decay profiles, and magnetic field effects on fluorescence showed that fluorinated derivatives of diphenylhexatriene were singlet fission materials. The rate constant of singlet fission was estimated as a function of temperature from the initial rate of decay of the fluorescence profiles. The origin of the temperature dependence was discussed in relation to the molecular stacking structure of the crystals.
