Graphene and graphene-like materials may be formed by preparing a solution of a suitable polycyclic aromatic hydrocarbon (PAH) in a solvent that is immiscible with water (or other suitable underlying liquid). A suitably thin layer of the PAH solution is formed on the surface of a thin layer of water. The solvent is evaporated from the solution layer to form a film of PAH material organized in contiguous molecular discs. The organized PAH material may be further processed by careful removal or evaporation of the water layer to deposit the PAH residue on a desired surface. The PAH residue may then be heated to remove hydrogen atoms and form a carbon-enriched or wholly carbon, graphene structure.
