Abstract: | Triplet-Excitons in a mixed 1 : 1 anthracene—tetracyanobenzene single crystal are established by ESR-spectrocopy. These excitons (lifetime 0.5 msec) are characterized by a hopping frequency of v = 1.3 × 106 K at 300K. The temperature dependence of the ESR line shape indicates a phase transition of the crystal at Tt = 205K. Above and below the phase transition the exciton mobility is nearly temperature independent. |
