A “three‐way‐templating” strategy is proposed for the growth of patterned, mesoporous silica on a gold‐covered mica substrate. A model is suggested, as shown in the Figure, involving (from bottom to top) the co‐assembly of alkanethiol‐decorated gold surfaces, alkanethiol‐surfactant hetero‐bilayers, and surfactant‐silicate assemblies.
