Abstract: A metal organic framework Fe2(bdp)3 (BDP2?=1,4-benzenedipyrazolate) with triangular channels is particularly suited for C5-C7 separations of alkanes according to the number of branches in the molecule rather than by carbon number. The metal-organic framework can offer pore geometries that is unavailable in zeolites or other porous media, facilitating distinct types of shape-based molecular separations.

Abstract: Metal-organic frameworks of the family M2 (2,5-dioxido-1,4-benzenedicarboxylate) wherein M=Mg, Mn, Fe, Co, Cu, Ni or Zn are a group of porous crystalline materials formed of metal cations or clusters joined by multitopic organic linkers that can be used to isolate individual gases from a stream of combined gases. This group of adsorbant materials incorporates a high density of coordinatively-unsaturated MII centers lining the pore surfaces. These adsorbents are particularly suited for selective carbon dioxide/monoxide adsorption via pressure swing adsorption near temperatures of 313 K since they selectively adsorb carbon dioxide at high pressures in the presence of hydrogen, and desorb carbon dioxide upon a pressure decrease. The redox-active FeII centers in Fe2(dobdc) can be used for the separation of O2 from N2 and other separations based on selective, reversible electron transfer reactions.
