We report the fabrication of nano- to micro- structures from polycyclic aromatic hydrocarbons (PAHs) without derivatizing these molecules by directly self-assembling them in the gas phase with a thermal evaporation process. Eighteen PAHs, ranging from three to ten fused rings, were selected for proof-of-concept studies and all of these PAHs self assembled to ordered nano- to micro- structures and each PAH has its unique morphology under appropriate conditions.
