Examination of the question “is π-stacking a unique form of dispersion?” reveals that planarity, rather than aromaticity per se, facilitates especially strong interactions between polycyclic aromatic hydrocarbons.

Polycyclic Aromatic

The geometry-dependent self-assembling features of two PAHs, 1 and 2, is reported. The more planar 1 forms H-type supramolecular polymers, in a highly cooperative fashion by combination of H-bonding and π-stacking, with rod-like morphology. However, the highly distorted 2 interacts only by means of H-bonding yielding lamellar supramolecular structures.

Polycyclic Aromatic

We show that polycyclic aromatic hydrocarbon (PAH) chromophores that are linked between two five-membered rings can access planarized structures with reduced optical gaps and redox potentials. Two aceanthrylene chromophores were connected into dimer model systems with the chromophores either projected outward (2,2’-biaceanthrylene) or inward (1,1’-biaceanthrylene) and the optical and electronic properties were compared. Only the planar 2,2’-biaceanthrylene system showed significant reductions of the optical gaps (1 eV) and redox potentials in relation to the aceanthrylene monomer.<br>
