Pyrdine incorporation into the covalent organic framework COF‐1 resulted in a highly dense packing structure in which the pyridine occupies the hexagonal pore space between the COF layers. This optimizes pore aperture for quantum sieving of hydrogen isotopes and introduces flexibility at cryogenic temperatures into the system. The separation factor ( S D 2 /H 2) is about 10 at 22 K, which is the highest reported to date.
