Porous alumina templates have been used to prepare dendrimer nanotubes with uniform size and orientation as well as high aspect ratios by a layer‐by‐layer deposition technique (see SEM image). The tubes may be released from or located in the template pores. Diffusion limitations arising from the pore geometry lead to tube segments with higher mechanical stability when located adjacent to pore openings compared to those located at the base of the pores.
