In the method, a polymerisable monomer is reacted in the presence of inorganic Nanocrystalline Cellulose (NNC) to provide a solid inorganic material with cellulose nanocrystals embedded in an organization nemu00e1tica chiral.The NCC can be removed to provide a stable porous structure that maintains the chiral organization of mould of NCC. The new materials can be obtained as independent films iridescent with large surface area. By controlling the reaction conditions, the color of the films can be varied throughout the visible spectrum.These are the first materials to combine the mesoporosidade with long range chiral order, which leads to the photonic properties.Examples of possible applications of the materials are: reinforcing materials of light weight materials with low k dielectric reflective tunable filters, adsorbents, stationary phases for chromatography of chiral substances or non chiral, supports for catalysts (for example, P. For asymmetric synthetic transformations).And as a mold to generate other new porous materials (for example, porous carbon or metal porous), preferably with nemu00e1ticas chiral structures.
