1. A method for the separation of carbon dioxide from a mixture, comprising contacting the mixture with a sorbent comprising a metal organic framework (MOF), wherein the MOF comprises:
a plurality of secondary building units (SBUs), each SBU comprising a repeating unit of one metal cation connected to another metal cation via a first moiety of an organic linker;
a layer of connected adjacent SBUs in which a second moiety of the linker in a first SBU is connected to a metal cation of an adjacent SBU, and
wherein adjacent layers are connected to each other via linker-to-linker bonding interactions; and
wherein each metal ion is selected from cobalt(II) ions, manganese(II) ions and nickel(II) ions, the organic linker is 5-aminoisophthalate, the first moiety is a carboxylate group and the second moiety is an amino group.
