Abstract

Singlet fission and triplet-triplet annihilation have attracted much attention in recent years due to their potential application to organic photo devices. In both processes, triplet pairs are generated as an intermediate, which determined the efficiency of these processes. We have observed magnetic field effects on triplet pairs generated in organic crystals with magnetic fields up to 10 T. The trace of an exchange coupled triplet pair was found using a steady-state measurement. We determined the structure of the exchange coupled triplet pair together with the magnitude of the exchange interaction in the pair.
