A very good host : The crystalline capsular structure of para ‐octanoylcalix[4]arene (see picture) is a promising adsorbent for saturated and unsaturated hydrocarbons, polarizable inert gases, and for carbon dioxide. The constant movement of acyl chains creates the effect of “soft cavity walls” in the calixarene capsule and allows gas adsorption even without permanent channels.
