Tubes from tubes: Microporous organic nanotubes were prepared by Sonogashira coupling between tetrakis(4-ethynylphenyl)methane and N,N′-di(4-iodophenyl)-4,4′-bipyridinium dichloride. These nanotubes were used as a template for secondary inorganic materials, namely Fe2O3 nanotubes with a high discharge capacity and excellent stability.
