Precise sub-Ångstrom-level porosity engineering, which is appealing in gas separations, has been demonstrated in solid carbon, polymer, and framework materials but rarely achieved in the liquid phase. In this work, a gas molecular sieving effect in the liquid phase at sub-5 Ångstrom scale is created via sophisticated porosity tuning in calixarene-derived porous liquids (PLs). Type II PLs are constructed via supramolecular complexation between the sodium salts of calixarene derivatives and crown ether solvents.

- * A new class of ionic liquids containing unique carbanion structures is utilized to enable the successive binding of two CO molecules through specific chemical bond formations, improving utilization of active sites.
- * Experimental techniques like spectroscopy and computational chemistry validate the findings, emphasizing that optimizing the molecular structure can significantly enhance CO capture performance while minimizing energy requirements for sorbent regeneration.
