Solid-state NMR techniques are used to study the effect of theinclusion of toluene and benzene on the mobility ofp-tert-butylcalixarene. We attribute the great increase inhost mobility upon complexation to the lack of strongdirectional intermolecular interactions. The differences inthe behaviour of the host in the two complexes are explainedin terms of the steric effects of the guest methyl group.
