INORGANIC MESOPOROUS MATERIALS WITH CHIRAL NEMATIC STRUCTURES AND PREPARATION METHOD THEREOF

摘要

The present invention describes the composition and method with chiral tissue production Metaporous silicon dioxide material. In the method, polymerizable inorganic monomer reacts in the presence of nanocrystalline cellulose (NCC), to obtain the solid inorganic material with the Cellulose nanocrystal being embedded in Chinrally nematic tissue. NCC can be removed, and obtain stable porous structure, retain the chiral tissue of NCC templates. New material can obtain the rainbow stick-up film with high surface area. By controlling reaction condition, the color of film can be changed over the entire visual spectrum. These are that the first is orderly combined mesoporous with remote chirality, so as to cause the material of photonic properties. The example of the possible application of these materials is: lightweight reinforcing material, low k dielectric, regulating reflection filter, adsorbent, for the stationary phase of chiral or achiral substances chromatography, for the carrier (for example, carrier) of catalyst. Converted for asymmetric synthesis), and other new porous materials (for example, porous carbon or porous metals) are generated as template, preferably there is chiral nematic structure.
