Insights into the thermodynamic–kinetic synergistic separation of propyne/propylene in anion pillared cage MOFs with entropy–enthalpy balanced adsorption sites

A chemically robust metal organic framework ZNU-2-Si with optimal pore chemistry and pore structure is reported for record C 3 H 4 storage and C 3 H 4 /C 3 H 6 separation by thermodynamic–kinetic synergism along with entropy–enthalpy balanced adsorption sites.
