We demonstrate a solution-based fabrication of centimeter-size free-standing films assembled from organic nanocrystals based on common dyes (perylene diimides, PDIs). These nanostructured exhibit good mechanical stability, and thermal robustness superior to most plastics, retaining the crystalline microstructure macroscopic shape upon heating up 250–300 °C. The show nonlinear optical response can be used as ultrafiltration membranes. functional materials small molecules alternative or complementary macromolecules.
