Thin Films: Patterning Polymer–Fullerene Nanocomposite Thin Films with Light (Adv. Mater. 7/2013)

The stability and association of polymer–fullerene films upon thermal annealing depends strongly on exposure to light, even at ambient conditions, as reported by João T. Cabral and co-workers on page 985. As a result, the coupling of self-assembly in polymer nanocomposites and photo-transformation provides an extremely promising route for patterning the stability (wetting/dewetting), morphology and characteristic dimensions in thin film composites.
