Bilayer stacks of nanoporous thin films presenting different composition, surface functionality and porosity in different scales are synthesised by a sequence of dip-coating and controlled post-treatments. Nanopatterning is achieved by supramolecular or phase separation templating. Different organic functions are included in each porous thin film layer by pre- or post functionalisation. The procedures presented here open the possibility to build complex stacked multilayer porous systems where a well-defined structure or function can be located in a predetermined place in space.
