Hydrogen-bond-directed self-assembly of perylene bisimide dyes bearing mesogenic bay substituents affords a new class of liquid crystalline materials which are suited to exploit the superb properties of perylene bisimide J-aggregates (intense fluorescence, long range exciton transport, high photostability) in thin film devices for photonics applications. Towards this goal tailored perylene bisimides will be synthesized which self-assemble in columnar, smectic and bicontinuous cubic mesophases. Their liquid-crystalline properties will be characterized in great detail by polarization microscopy, differential scanning calorimetry as well as SAXS/WAXS X-ray studies. Further supramolecular interactions between two complementary mesogenic compounds will be utilized to control the phase and ordering behavior as well as the functionality of the mesophase materials. By combining electron poor J-aggregated perylene bisimides with complementary electron rich conjugated oligomers such as oligothiophenes and oligophenylenevinylenes a new class of supramolecular p-n-heterojunctions will become accessible. The unique arrangement of the functional building blocks will lead to nanostructured materials that may transport excitons as well as electron/hole carriers.
