Abstract
Patterning of functional materials is of general importance, as it is the implementation of shapes into materials that enables them to perform functions at different levels of complexity. It is our ability of shaping materials that allows us to embed knowledge and information into them, at several lengthscales. This can be on a scale of 100 nm or so, as in two-dimensional photonic crystals, or on a few nanometres scale, as in certain supramolecular architectures whose properties rely on the particular shape of the molecular blocks that constitute them, and which interact via non-covalent interactions, as in conjugated polyrotaxanes made of conjugated polymers threaded into insulating cyclodextrin rings.
