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the presence of a nonaqueous organic solvent in the presence of and/or with liberation of water, wherein the latter is withdrawn from the liquid phase of the reaction mixture during the reaction.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.
