Tuning SF6 affinity via tailoring pore environments in metal–organic frameworks

Abstract

Herein, an investigation into the impact of subtle binding site changes on SF₆ affinity is presented by systematically altering the pore environment of MOF-808 via post-synthetic modification with aryl and benzylic fluoride groups. All functionalized derivatives outperform the parent material, with aryl fluorides increasing SF₆ uptake fourfold.
