Cucurbit[7]uril (CB[7]), in its amorphous solid state, shows one of the highest CO2 sorption capacities among the known organic molecular porous materials at 298 K and 0.1~ and 1 bar. Apart from the highest CO2 capacity, CB[7] shows a remarkable selectivity of CO2 over N2 and CH4. These properties along with the readily available precursors makes this materials a very attractive for CO2 sequestration particularly when considering the easy synthesis and low manufacturing costs.
