Claims
- 1. A process for producing a composite composition comprising a homogeneous inorganic oxide glass monolith with a microporous structure containing an organic component which exhibits nonlinear optical response, which comprises hydrolyzing tetraalkoxysilane under acidic or basic pH conditions in a sol-gel reaction medium comprising water, a water-miscible organic solvent and an organic component which exhibits nonlinear optical response, until gellation of the reaction medium is completed, and removing the solvent medium to provide a porous glass monolith with incorporated organic component.
- 2. A process in accordance with claim 1 wherein substantially all of the pores in the microporous structure have diameters within about a 100 angstrom diameter variation range.
- 3. A composite composition produced in accordance with the sol-gel process of claim 1.
- 4. A process for producing a composite composition comprising an inorganic oxide glass monolith with a microporous structure containing an organic component which exhibits nonlinear optical response, which comprises (1) hydrolyzing tetraalkoxysilane under acidic or basic pH conditions in a sol-gel reaction medium comprising water and a water-miscible organic solvent component until gellation of the reaction medium is completed; (2) removing the solvent medium to provide a porous glass monolith; and (3) impregnating the porous glass monolith with an organic component which exhibits nonlinear optical response.
- 5. A process in accordance with claim 4 wherein substantially all of the pores in the microporous structure have diameters within about a 100 angstrom diameter variation range.
- 6. A composite composition produced in accordance with the process of claim 4.
