In article number 2007412, Jitae T. Park, Hyunchul Oh, and co‐workers report a hydrogen‐isotope separation mechanism in the flexible framework of [MIL‐53(Al)] through a diffusion dynamics study by quasielastic neutron scattering measurements. The dynamic breathing of the flexible pores allows faster diffusion of the heavier isotope at high temperature, unlike in rigid frameworks.
