Enhancement of gas-framework interaction in a metal-organic framework by cavity modification

Originated from the pore space segmentation modification of a reported metal-organic framework (MOF) (NOTT-125), a new porous MOF ZnX was obtained and characterized by single-crystal X-ray diffraction, elemental analysis, X-ray powder diffraction and TGA. The ZnX exhibits remarkable selective CO2 adsorption property compared with that of the NOTT-125, which should be attributed to the enhanced gas-framework interactions induced by the fragmented pore space in ZnX.
