We report a useful lithographic technique for the fabrication of organic or metal films on wettability-patterned surfaces fabricated solely through self-assembly. The phase-separated structures in mixed Langmuir-Blodgett (LB) films can be tuned by adjusting intermolecular interactions in film-forming molecules such
