Well-defined mesoscopic structures are obtained by self-organization of a multifunctional perylene chromophore that is highly photostable, has a high fluorescence quantum yield, and distinct redox activity. Transmission electron microscopy (see Figure) of such a mesoscopic superstructure, along with NMR and optical spectroscopy, reveals a hierarchical process involving various intermolecular interactions.
