Rational design of phosphonocarboxylate metal–organic frameworks for light hydrocarbon separations

Author affiliations

Abstract

Metal–organic frameworks (MOFs) provoke intensive research interests on separations of small gas molecules. By introducing a coordinative phosphate group into a carboxylic acid linker, a ligand 4,4′-(hydroxyphosphoryl) dibenzoic acid (H3hpda) was successfully synthesized and used to construct microporous phosphonocarboxylate framework [Cu3(hpda)2·DMF·2H2O]·3DMF·H2O (DMF = N,N-dimethylformamide) and [Mg32-OH2)2(OH2)2(hpda)2]·3DMF·2H2O. Both of them possess narrow approachable channels and exhibit excellent performance on selective separation of light hydrocarbons (C1–C2), presenting a promising ligand design strategy for the construction of porous material aiming for natural gas upgrading.
