title: Directed spatial organization of zinc oxide nanorods.
abstract: The ability to precisely place nanomaterials at predetermined locations is necessary for realizing applications using these new materials. Using an organic template, we demonstrate directed growth of zinc oxide (ZnO) nanorods on silver films from aqueous solution. Spatial organization of ZnO nanorods in prescribed arbitrary patterns was achieved, with unprecedented control in selectivity, crystal orientation, and nucleation density. Surprisingly, we found that caboxylate endgroups of omega-alkanethiol molecules strongly inhibit ZnO nucleation. The mechanism for this observed selectivity is discussed.
