Abstract
The present invention relates to a process for preparing porous organic frameworks by reaction of a reaction mixture in a liquid phase comprising the appropriate starting compounds in the presence of a nonaqueous organic solvent in the presence of and/or with liberation of water, wherein the latter is withdrawn from the liquid phase of the reaction mixture during the reaction. Here, frameworks having relatively high specific surface areas can be obtained in a reproducible way.
Claims10
A process for preparing a porous metal organic, if appropriate limited, framework, which comprises the step
- reaction of a reaction mixture in a liquid phase comprising at least one metal compound with at least one at least bidentate organic compound which can be coordinated to the metal, in the presence of a nonaqueous organic solvent in the presence of and/or with liberation of water, with the organic compound having at least two atoms selected independently from the group consisting of oxygen, sulfur and nitrogen via which the organic compound can coordinate to the metal, wherein water is withdrawn from the liquid phase of the reaction mixture during the reaction.
A process for preparing a porous organoboron framework, which comprises the step
- reaction of a reaction mixture in a liquid phase comprising at least one compound having at least two boronic groups with at least one at least bifunctional organic compound which can be covalently bound to a boronic group, in the presence of a nonaqueous organic solvent, with the at least bifunctional organic compound having at least two atoms selected independently from the group consisting of oxygen, sulfur and nitrogen via which the bifunctional organic compound can be covalently bound to a boronic group, wherein water is withdrawn from the liquid phase of the reaction mixture during the reaction.
