(57) [Problem] To obtain a new organic-inorganic composite and an inorganic material using an organic low-molecular gel as a template. SOLUTION: It is obtained from a low organic molecule capable of forming a gel in an organic solvent or a mixed solvent of an organic solvent and water having an ionic site, and a sol-gel reaction solution containing a precursor of a metal oxide. After a low-molecular organic gel is formed in the mixed solution, the polymerization of the metal oxide proceeds while maintaining the gel-forming system, so that the inside is an organic molecule and the outside is a metal oxide on the order of nanometers. An organic-inorganic composite having a cylindrical structure is obtained. Furthermore, a hollow fiber-shaped metal oxide can be obtained by removing organic low molecules from the organic-inorganic composite. A preferred example of the organic low molecular weight is a cholesterol derivative having an ionic moiety and an azobenzene moiety, and the metal oxide is, for example, silica. |
