PREPARATION OF SURFACE FUNCTIONALIZED POROUS ORGANIC-INORGANIC HYBRID MATERIALS OR MESOPOROUS MATERIALS WITH COORDINATIVELY UNSATURATED METAL SITES

摘要

A method for preparing a surface-functionalized porous organic-inorganic hybrid material or mesoporous material is provided to be applicable to an adsorber, a gas storage material, a sensor, a membrane, a functional thin film, a catalyst, a catalyst carrier and the like. A method for preparing a surface-functionalized porous organic-inorganic hybrid material or mesoporous material comprises reaction of porous organic-inorganic hybrid materials having coordinatively unsaturated metal sites with at least one compound selected from silane, an organic metal compound and polyoxometallate. Particularly, the porous organic-inorganic hybrid material is a crystalline polymer compound of a microporous structure, which is formed by combination of a core metal ion thereof with an organic ligand. In the method, the reaction comprises depositing the silane or the organic metal compound onto the porous organic-inorganic hybrid material, or introducing the porous organic-inorganic hybrid material into a solution of the organic metal compound or polyoxometallate.
