Gases as guests in benzocyclotrimer cage hosts.
An imine-linked (+)-syn-benzotricamphor derivative gives access to chiral unimolecular cages exhibiting internal cavities of new shapes and volumes. One of these hosts hydrocarbon gases at low temperatures in solution through CH-pi attractive interactions. No encapsulation is observed when the cage structure is too narrow or too large for the guest.
