Hysteretic sorption of light gases by a porous metal–organic framework containing tris(para-carboxylated) triphenylphosphine oxide

Abstract

The porous metal-organic framework (MOF) PCM-4, based on tris(para-carboxylated) triphenylphosphine oxide, contains atypical, polar organic substituents; the material exhibits a hysteretic sorption of Ar, N2 and O2, and demonstrates the advantage of ligands of this type.
