Size‐Selective and Reversible Encapsulation of Single Small Hydrocarbon Molecules by a Cavitand–Porphyrin Species

Abstract

An accommodating host: A new capsule-shaped host molecule, the cavitand–porphyrin shown, reversibly encapsulates single hydrocarbon molecules smaller than propane (see picture). With the exception of acetylene, the binding affinities are inversely correlated with the size of the guest hydrocarbons.
