(Chemical Equation Presented) A hexagonal web of carboxylic-terminated nanostripes (left image, bright areas) is patterned onto a methyl-terminated surface of an octadecyltrichlorosilane monolayer. A thermally annealed polystyreneblock-poly(ethylene oxide) (PS-b-PEO) thin-film, spin-cast on the chemical pattern (right image), exhibits surface normal oriented cylindrical PEO microdomains on the methyl-terminated regions only. These chemical patterns effectively template the order and spatial orientation of diblockcopolymer microdomains. © 2010 WILEY-VCH Verlag GmbH & Co. KCaA, Weinheim. Source
