A porous molecular crystal assembled by close‐packing of macrocyclic cyclotetrabenzoin acetate efficiently captures CO 2 , as reported by Ognjen Š. Miljanić, Teng‐Hao Chen et al. in their Research Article on page 14931. The square 7.1×7.1 Å pores enable excellent CO 2 /N 2 and CO 2 /CH 4 separation performance via both kinetic and thermodynamic effects. Moderately strong CO 2 –framework interactions allow easy regeneration of the adsorbent and its use in pressure swing adsorption.
