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.

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.

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>
