Abstract: In recent years the development of new methods of storing, trapping or separating light gases, such as CO2, CH4 and CO has become of utmost importance from an environmental and energetic viewpoint. Porous materials such as zeolites and porous organic polymers have long been considered good candidates for this purpose. More recently, metal organic frameworks (MOFs) have attracted further interest with many aspects of their functional and mechanical properties investigated. The porous channels found in MOFs are ideal for the uptake of guests of different shapes and sizes, and with careful design they can show high selectivity for particular species from a mixture.1 Adsorption properties of MOFs have been thoroughly studied,2 however obtaining in depth ‘structural’ insight into the adsorption/desorption mechanism is not so common place. For example, out of ca. forty thousand published framework structures there are less than 60 entries in which CO2 molecules have been experimentally located within the pores.
