Figure 4: Periodic potentials introduced by the supramolecular lattices.

Calculated differential electrical potential induced by a supramolecular lattice of (a) MBB-1 and (b) MBB-2 on graphene. The supramolecular lattice is superimposed for clarity. The electrical potential is periodically modulated, with negative values in the region below the molecular heads. Carbon atoms are shown in grey, hydrogen in white, nitrogen in red, fluorine in light blue and chlorine in green.
