摘要:
The invention relates to a porous metal-organic framework material for taking up at least one substance, the framework material comprising at least one at least bidentate organic compound bound by coordination to at least one metal ion, and the framework material having at least in part pores which comprise a polymer which is suitable to adsorb the at least one substance. In addition, the invention relates to a method for producing the framework material, a method for taking up at least one substance by the framework material and also to the use of the framework material, in particular for the storage, separation, controlled release or chemical reaction of a substance taken up.
