Inside Back Cover: N ‐Annulated Perylene Bisimides to Bias the Differentiation of Metastable Supramolecular Assemblies into J‐ and H‐Aggregates (Angew. Chem. Int. Ed. 40/2020)

The self‐assembling features of N ‐annulated perylene bisimides (PBIs) 1 and 2 are discussed by E. Ortí, L. Sánchez, and co‐workers in their Research Article on page 17517. The stability of the aggregates of diester 1 substantiates the significance of van der Waals and dipole–dipole electrostatic interactions in the construction of stable supramolecular assemblies. The incorporation of amide functional groups in 2 results in a stimulating pathway differentiation to achieve up to three J‐type aggregates and a fourth H‐type aggregate depending on the experimental conditions.
