Molecular gas works: p‐tert ‐Butylcalix[4]arene crystals possess large interstitial cavities when grown by sublimation and, although nonporous, are able to absorb and retain gases such as O 2 , N 2 , and CO 2 under near‐ambient conditions. H 2 is not retained and thus the material can be used to effect the separation of H 2 from gas mixtures. The gas can be removed by evacuation or immersion of the crystals in nitrobenzene (see picture).
