Abstract
The present invention relates to methods of preferentially sorbing, from a target mixture, one or more target substance(s) over one or more non-target substance(s). In particular, porous organic cages (POCs) may be deployed in the quantum sieving of mixtures of hydrogen isotopes to selectively sorb heavy hydrogen isotopes (e.g. diatomic deuterium) over lighter isotopes (diatomic protium).
