Abstract Membrane technology has been explored for separating helium from hydrogen in natural gas reservoirs, a process that remains extremely challenging due to the sub‐Ångstrom size difference between H 2 and He molecules. Reverse‐selective /He separation membranes offer multiple advantages over conventional helium‐selective membranes, which, however, suffer low selectivity. To address this hurdle, novel approach is proposed tune ultra‐micropores of carbon molecular sieves (CMS) through fluorination polymer precursor. By incorporating ‐CF 3 units into backbone Tröger's base polymers, microporosity CMS tailored reverse‐selective are deployed with remarkable performance, surpassing most reported membranes. These exhibit permeability 1505.2 Barrer notable selectivity 3.8. Barometric sorption tests reveal preferential fluorinated which also demonstrate significantly higher diffusion compared unfluorinated samples. Material studio calculations indicate “slim” molecule penetrates more readily than spherical molecule, thus achieving reverse This design offers promising pathway developing molecularly sieving tackle gas.
