Organic-inorganic compound material obtained in high yield without drying, useful in production of lenses, thin films, particles, and fibers

摘要

A process for the preparation of a compound material from organic and inorganic compounds without a drying stage and with a high yield of the compound material is new. A mixed solution of a metal alkoxide and a silicon-containing compound is reacted with a catalyst, to give an alkogel of a metal oxide or a metal oxide complex. The metal oxide is prepared by reaction of at least one metal with an alcohol, the mixed solution is prepared by mixing the metal oxide with the silicon-containing compound, and the alkogel obtained has a lattice structure. The alkogel is centrifuged, to separate the alcohol from the inorganic lattice structure, a gel is formed, an organic monomer is added to the gel, and the monomer is polymerized. An Independent claim is included for addition to the mixed solution of a compound containing a functional extraneous material having optical properties, e.g. an Eu<3>+ ion.
