Control of Two‐Dimensional Nanopatterns by Adjusting Intermolecular Interactions

Abstract

Ultrathin films of small organic molecules are patterned with nanostructures, the size of which is controlled by adjusting intermolecular interactions. Nanowires of controllable widths form in the mixed Langmuir–Blodgett (LB) films of long-chain fatty acid and hybrid carboxylic acid (see figure). Templates, which can confine both organic and inorganic materials, are fabricated from three-component LB films, containing an amphiphilic silane-coupling agent.
