Cover Picture: Crosslinked Nanoparticle Stripes and Hexagonal Networks Obtained via Selective Patterning of Block Copolymer Thin Films (Adv. Mater. 18/2005)

17_18/2005The construction and fixation of ordered nanoparticle arrays allow not only the exploitation of the array's collective physical properties but also the possibility of manipulating discrete aggregates within a larger-scale assembly scheme. A simple approach utilizing block copolymer thin films as templates and coordination chemistry as a mild crosslinking mechanism is reported by Shenhar, Rotello, and co-workers on p. 2206. The cover image (by Nicholas Fischer) shows terpyridine-functionalized gold nanoparticles organized in stripes on top of a microphase-separated thin film of polystyrene-block-poly(methyl methacrylate) and crosslinked thorough the formation of iron–bisterpyridine complexes.
