Topology meets MOF chemistry for pore-aperture fine tuning: ftw-MOF platform for energy-efficient separations via adsorption kinetics or molecular sieving.

Herein we demonstrate how the combined use of the molecular building block (MBB) approach and reticular chemistry allows the fabrication of a highly stable, ultra-microporous metal-organic framework (MOF) that is an efficient sorbent for the challenging separation of propane/propylene.
