Methods for Associating or Dissociating Guest Materials with a Metal Organic Framework, Systems for Associating or Dissociating Guest Materials Within a Series of Metal Organic Frameworks, and Gas Separation Assemblies

An electrochemical cell comprising:

• at least two individual cells;
• one of the two cells comprising metal organic framework having one oxidation state;
• another of the two cells comprising metal organic framework having another oxidation state, the one oxidation state being different than the other oxidation state.

A method of separating carbon dioxide from a mixture comprising carbon dioxide, the method comprising:

• providing a mixture to at least one cell and associating the carbon dioxide of the mixture with a metal organic framework of the one cell;
• and
• altering the oxidation state of the metal organic framework to disassociate at least some of the carbon dioxide from the metal organic framework.

A method of separating one or more carbon compounds from a mixture comprising carbon compounds, the method comprising:

• providing a mixture to at least one cell and associating the carbon compound of the mixture with a metal organic framework of the one cell, the carbon compound comprising C and at least one or more of Cl, F, Br, and H;
• and
• altering the oxidation state of the metal organic framework to disassociate at least some of the carbon compound from the metal organic framework.
