The unique self-assembling features ofN-annulated perylene bisimides (PBIs)1and2are reported. The stability of the aggregates of diester1, in which no H-bonding interactions are operative, corroborates the significance of long-range van der Waals and dipole-dipole electrostatic interactions in the construction of stable supramolecular assemblies. The incorporation of amide functional groups within theN-annulated PBI in2stimulates pathway differentiation to achieve up to three J-type aggregates and a fourth H-type aggregate depending on the experimental conditions. The results presented demonstrate unprecedented levels of control over synthetic supramolecular self-assembly and the rich differentiation thatN-annulated PBIs exhibit, opening the door to new, complex, functional supramolecular materials.
