A microporous metal-organic framework with unusual 2D → 3D polycatenation for selective sorption of CO2 over CH4 at room temperature

A new microporous polycatenated MOF with open Lewis basic sites has been designed. This MOF shows excellent adsorption selectivity for CO2 over CH4 around room temperature, which has been correlated to its microporous structure and the specific interaction of CO2 with functional azine groups that decorated the pore channels.235
