1. A method for releasing associated guest materials from a metal organic framework the method comprising 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 (M2+/M3+). 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 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.

The system of claim 21 further comprising a conduit extending to a valve in fluid communication with both the metal organic frameworks. 26. The system of claim 25 further comprising: a power source;a motor configured to operate the valve; anda controller operatively coupled to the power source, the metal organic frameworks, and the motor. 27. A gas separation assembly comprising: a plurality of individual cells housing metal organic framework, the plurality comprising at least one series of cells and another series of cells, each series comprising at least two electrically isolated individual cells;a channel between the one series of cells and the other series of cells;a power source; anda controller coupled to both the assembly and the power source. 28. The assembly of claim 27 wherein the channel comprises an electrolyte. 29. The assembly of claim 27 wherein the one series is aligned laterally of the other series, and the individual cells of the one series are aligned lateral to the individual cells of the other series to form a pair of cells. 30. The assembly of claim 29 wherein one of the pair of cells is configured to dissociate guest materials, and the other of the pair of cells is configured to associate guest materials. 31. The assembly of claim 29 further comprising conduits extending along the perimeter of each of the series of cells, the conduits configured to expose the metal organic framework of each of the cells of each of the series. 32. The assembly of claim 31 wherein the one series of cells is in fluid communication with one conduit, and the other series of cells is in fluid communication with another conduit.
