1. A method, comprising:
contacting a solvent with a porous cyclodextrin metal organic framework (CD-MOF) adsorbed with CO2 to release CO2; and
collecting the released CO2, wherein the CD-MOF includes metal cations and a cyclodextrin, the cyclodextrin having the formula:

OG Complex Work Unit Drawing
wherein n is an integer ranging from 0 to 10; R is an —OH group, and, the metal cations coordinate to a primary face C6 —OH group and glycosidic ring oxygen atom of glycosidic rings of the cyclodextrin, or, to secondary face C2 and C3 —OH groups of alternating glycosidic rings of the cyclodextrin.
