Abstract

A liquid-crystalline dibenzophenazine that was forced to adopt a head-to-head stacking arrangement to generate a large dipole moment adapted to this stacking by hierarchical assembly into a 2D hexagonal superlattice (see picture). Thus, the net dipole and the contact area between immiscible side chains were minimized. Homeotropic alignment of the assembly on glass gave rise to directional charge transport.
