FIELD: chemistry. n SUBSTANCE: invention describes a composition and a method of obtaining mesoporous silica materials with a chiral structure. In accordance with the method an inorganic monomer to be polymerised interacts in the presence of nanocrystalline cellulose NCC) with nanocrystals of cellulose, included into the chiral nematic structure with the formation of an inorganic solid substance material. NCC can be removed with the formation of a stable porous structure, which preserves the chiral structure of NCC template. The material can be obtained in the form of a rainbow freely located film with the high surface area. The obtained materials can be used as lightened reinforced materials, dielectric materials, tuneable reflecting filters, adsorbents, stationary phases for the separation of chiral or achiral substances, substrates for catalysts, and as a template for the creation of other porous materials, preferably with chiral nematic structures. n EFFECT: invention makes it possible to obtain the novel type of materials, combining mesoporosity with a long-range chiral order, which provides photon properties. n 32 cl, 21 dwg, 5 ex |
