Abstract
Dynamical behavior of Frenkel excitons in aromatic hydrocarbon crystals, pyrene, α-perylene, β-perylene, and tetracene are overviewed based on the published references and in terms of the self-trap depth. Then pressure-induced instability in exciton states (the change in the self-trap depth) in α-perylene and anthracene is demonstrated and discussed. Finally a quasi-free exciton state is suggested to be the origin of the luminescence in anthracene at room temperature.
