Original, complex macroporous architectures made of metal or conducting polymers can be obtained by using the Langmuir–Blodgett technique for the elaboration of colloidal superstructures as templates. As reported by Serge Ravaine, Alexander Kuhn, and co-workers on page 538, porosity gradients are synthesized with control of the pore size at the single pore layer level. The obtained materials present features that provide a pathway to interesting applications ranging from electrochemistry to catalysis and photonics.
