ORGANIC/INORGANIC COMPOSITE BODY HAVING SPIRAL STRUCTURE HAVING CONTROLLED SPIRAL DIRECTION, METAL OXIDE AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a technique for manufacturing a micro structural body having a spiral structure useful as a catalyst for a reaction, in which chirality participates, and having a fixed direction. SOLUTION: The manufacturing method of an organic/inorganic composite body formed by depositing the metal oxide on the surface of a chiral organic compound having the fixed directional spiral structure comprizes (1) a process for preparing (a) a mixture of an ionic chiral organic compound capable of forming a gel in a solvent with a nonionic chiral organic compound having the same chirality as the said organic compound and capable of forming a gel in a solvent and (b) a sol-gel reaction solution containing a metal oxide polymer formed from a precursor of the metal oxide by a sol-gel reaction, (2) a process for forming the gel of the organic chiral compound by (a) removing the solvent from the uniform liquid mixture, (b) cooling the uniform liquid mixture after heating or (c) cooling the uniform liquid mixture and (3) a process for holding the system, in which the gel is formed, and advancing the polymerization of the metal oxide.
