Dispersoid having metal-oxygen bonds, metal oxide film, and monomolecular film

摘要

Dispersoids having metal-oxygen groups that are suitable for the production of metal oxide thin-films at a low temperature of 200° C. or below and for the production of homogeneous organic-inorganic hybrid materials. The dispersoid having metal-oxygen bonds may be obtained by mixing a metal compound having at least three hydrolyzable groups with at least 0.5 mole but less than 2 moles of water per mole of the metal compound in an organic solvent, in the absence of an acid, a base, and/or a dispersion stabilizer, and at a temperature at or below the temperature at which the metal compound begins to hydrolyze, then raising the temperature to at least the temperature at which hydrolysis begins.
