present the synthesis of a shape‐persistent cage compound by the reversible formation of 24 boronic ester units of 12 triptycene tetraol molecules and 8 triboronic acid molecules. The cage compound bears a cavity of a minimum inner diameter of 2.6 nm and a maximum inner diameter of 3.1 nm, as determined by single‐crystal X‐ray analysis. The porous molecular crystals could be activated for gas sorption by
