In the condensed phase, these polyaromatic molecules are heldtogether by relatively weak interactions between their electric quadropoles and by vander Waals forces. Perylene and its derivatives have attracted significant interest as activelayers for light harvesting, photovoltaics, and photoinduced charge and energy transferprocesses. This thesis focuses mainly on crystals of perylene-based molecules becausethese substances areamongthe bestcharacterized organicmaterials.
