Abstract

This paper demonstrates both experimental and theoretical analysis of the Coulomb attraction of CT excitons, assembling n-string excitons in a quasi-one-dimensional charge transfer (CT) organic crystal. The excitonic strings were experimentally investigated by applying an ultrafast pump-probe study on high caliber anthracine-PMDA crystals more than 50 μm thick. It was observed that an increase in pump intensity provoked another absorption band at even lower energy. Furthermore, the experimental and theoretical spectra were adequately in agreement with each other.
