The supramolecular assembly of surfactant molecules at a solid­
liquid interface can produce tubular structures with diameters of
around 10 nm (refs 1­4), which can be used for the templated
polymerization of mesoporoussilica thin films3­5
. The orientation
of the tubules depends primarily on the nature of the substrate­
surfactant interaction. These nanostructured films hold much
promise for applications such as their use as orientated nano-
