“…Permanent porosity was demonstrated experimentally through gas sorption experiments in just five: , each of which is distinct in terms of structure. [26] Additionally, the 3,5-connected net of formula [Cu(tepb)(SO 4 )] has been reported without sorption data and is also distinct from the 4,6-connected fsc net reported herein. [27] To our knowledge, SOFOUR-1-Zn is not only prototypal for a new HUM platform, it is the first SO 4 2À -based porous coordination network of any type to be studied for gas separations.…”

Hybrid ultramicroporous materials, HUMs, are comprised of metal cations linked by combinations of inorganic and organic ligands. Their modular nature makes them amenable to crystal engineering studies, which have thus far afforded four HUM platforms (as classified by the inorganic linkers). HUMs are of practical interest because of their benchmark gas separation performance for several industrial gas mixtures. We report herein design and gramscale synthesis of the prototypal sulfate-linked HUM, the fsc topology coordination network ([Zn(tepb)(SO 4 )] n ), SO-FOUR-1-Zn, tepb = (tetra(4-pyridyl)benzene). Alignment of the sulfate anions enables strong binding to C 2 H 2 via O•••HC interactions but weak CO 2 binding, affording a new benchmark for the difference between C 2 H 2 and CO 2 heats of sorption at low loading (ΔQ st = 24 kJ mol À 1 ). Dynamic column breakthrough studies afforded fuel-grade C 2 H 2 from trace (1 : 99) or 1 : 1 C 2 H 2 /CO 2 mixtures, outperforming its SiF 6 2À analogue, SIFSIX-22-Zn.

HUMs are of practical interest because of their benchmark gas separation performance for several industrial gas mixtures. We report herein design and gram‐scale synthesis of the prototypal sulfate‐linked HUM, the fsc topology coordination network ([Zn(tepb)(SO4)]n), SOFOUR‐1‐Zn, tepb=(tetra(4‐pyridyl)benzene). Alignment of the sulfate anions enables strong binding to C2H2 via O⋅⋅⋅HC interactions but weak CO2 binding, affording a new benchmark for the difference between C2H2 and CO2 heats of sorption at low loading (ΔQst=24 kJ mol−1). Dynamic column breakthrough studies afforded fuel‐grade C2H2 from trace (1 : 99) or 1 : 1 C2H2/CO2 mixtures, outperforming its SiF62− analogue, SIFSIX‐22‐Zn.
