First claim

The invention claimed is:

1. A method for releasing associated guest materials from a metal organic framework, the method comprising electrically altering the oxidation state of at least a portion of the metal of the metal organic framework to dissociate at least a portion of the guest materials from the framework.

2. The method of claim 1 wherein the portion of the metal of the metal organic framework is a transition metal.

3. The method of claim 1 wherein the portion of the metal of the metal organic framework is one or more of Ti, Zr, Hf, Rf, V, Nb, Ta, Db, Cr, Mo, W, Sg, Mn, Tc, Re, Bh, Fe, Ru, Os, Hs, Co, Rh, Os, Hs, Co, Rh, Ir, Mt, Ni, Pd, Pt, Ds, Cu, Ag, Au, and Rg.

4. The method of claim 1 wherein the portion of the metal of the metal organic framework has a mixed oxidation state.

5. The method of claim 1 wherein the portion of the metal of the metal organic framework is represented as (M 2+ /M 3+ ).

6. The method of claim 1 wherein the portion of the metal of the metal organic framework is coupled to a substantially conductive organic ligand.

7. The method of claim 1 wherein the guest material comprises carbon dioxide.

8. A method for associating guest materials with a metal organic framework, the method comprising electrically altering the oxidation state of at least a portion of the metal of the metal organic framework to associate at least a portion of the guest materials with the framework.

9. The method of claim 8 further comprising exposing a mixture to the metal organic framework, the mixture comprising the guest materials and other materials, at least a portion of the other materials not being associated with the metal organic framework upon the exposing.

10. A method for selectively associating or dissociating guest materials with a metal organic framework, the method comprising electrically altering the oxidation state of at least a portion of the metal of the metal organic framework to associate or dissociate at least a portion of the guest materials with the framework.

11. The method of claim 10 further comprising exposing a mixture to the metal organic framework, the mixture comprising the guest materials and other materials, at least a portion of the other materials not being associated with the metal organic framework upon the exposing.

12. The method of claim 11 wherein during the exposing, guest material is associated with the metal organic framework.

13. The method of claim 12 further comprising:
ceasing the exposing;
altering the oxidation state of the portion of the metal; and
dissociating at least a portion of the guest materials from the metal organic framework.

14. The method of claim 13 further comprising:
after the dissociating, altering the oxidation state of the portion of the metal to return the oxidation state to an associating oxidation state;
after the altering, exposing the mixture to the metal organic framework; and
associating at least a portion of the guest material of the mixture with the metal organic framework.

15. The method of claim 10 wherein the altering comprises applying a predetermined voltage to the metal organic framework.

16. The method of claim 10 wherein the oxidation state of the portion of the metal is electrochemically altered.
