The supramolecular aggregation of three diimidazolium-functionalized perylene bisimides, differing in thealkyl chain length was investigated. These salts form aggregatesin solvents like chloroform, dichloromethane, and glycerol.Solvent-, concentration-, and temperature-dependentspectroscopic studies were carried out, evidencing the occurrenceof an isodesmic, enthalpy-driven aggregation process,underpinned by p–p stacking and hydrogen bonding.Moreover, dynamic light scattering (DLS) measurements andSEM images revealed that these salts aggregate in chloroforminto elongated structures.
