What's in a name? The phrase “aromatic interactions” is widely used to describe noncovalent interactions involving aromatic rings. However, computed stacking energies suggest that disruption of the aromatic π delocalization can enhance many of these interactions and also render them orientation-dependent. Because of these effects, the use of nonaromatic systems should be advantageous in supramolecular chemistry.
