Abstract

A highly robust porous hydrogen-bonded organic framework (HOF) constructed by 4,4′,4′′-benzene-1,3,5-triyl-tris(benzoic acid) not only achieves the highest uptakes of ethylene and ethane among the HOF materials, but also exhibits unusual adsorption selectivity of C₂H₆ over other C₂ gases. Besides, it exhibits the second highest acetylene uptake among all the reported HOF materials.
