Porous organo-metallic skeleton material containing an additional polymer
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.
1. 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 pores at least in part which comprise a polymer which is suitable for absorbing the at least one substance.
2. The framework material according to claim 1 , wherein the framework material comprises Mg, Ca, Fe, Zn, Al, Ni or Cu as metal ion and the at least bidentate organic compound is selected from the group consisting of terephthalic acid, isophthalic acid, 2,6-naphthalenedicarboxylic acid and 1,3,5-benzenetricarboxylic acid.
3. The framework material according to claim 1 , wherein at least 5% by weight and at most 95% by weight of the maximum possible amount taken up in the framework material of the polymer-forming monomer(s) are used.
4. The framework material according to claim 1 , wherein the at least one substance is a gas.
5. The framework material according to claim 1 , wherein the polymer is selected from the group consisting of an aromatic polymer, a polyamide, a polyester, a polyether, a polyacetal, a polycarbonate, a polyacrylate and mixtures thereof.
6. The framework material according to claim 5 , wherein the polymer is a styrene-based polymer.
7. A method for producing a framework material according to claim 1 comprising
preparing a porous metal-organic framework material which can take up at least one substance comprising at least one at least bidentate compound bound by coordination to at least one metal ion;
contacting the metal-organic framework material with at least one monomer which is suitable for forming a polymer which can adsorb the at least one substance; and
converting the at least one monomer into said polymer.
8. A method for taking up at least one substance comprising contacting the at least one substance with a framework material according to claim 1 .
9. The method according to claim 8 , wherein the at least one substance is a gas selected from the group consisting of hydrogen, natural gas, town gas, methane, propane and butane.
10. A method of using a framework material according to claim 1 for taking up at least one substance for its storage, separation, controlled release or chemical reaction.
