Temperature-dependent molecular sieving of fluorinated propane/propylene mixtures by a flexible-robust metal-organic framework.

ABSTRACT: The electronics industry necessitates highly selective adsorption separation of hexafluoropropylene (C₃F₆) from perfluoropropane (C₃F₈), which poses a challenge due to their similar physiochemical properties. In this work, we present a microporous flexible-robust metal-organic framework (Ca-tcpb) with thermoregulatory gate opening, a rare phenomenon that allows tunable sieving of C₃F₈/C₃F₆. Remarkably, the temperature-dependent adsorption behavior enhances the discrimination between the larger C₃F₈ and the smaller C₃F₆, resulting in unprecedented C₃F₆/C₃F₈ selectivity (over 10,000) compared to other well-known porous
