Two molecules of cavitand tetraboronic acid and four molecules of various bis(catechol) linkers self-assemble into capsules through the formation of eight dynamic boronic ester bonds. Each capsule has a different cavity size depending on the linker used, and shows particular guest encapsulation selectivity. A chiral capsule made up of the cavitand and a chiral bis(catechol) linker was also constructed. This capsule induces supramolecular chirality with respect to a prochiral biphenyl guest by diastereomeric encapsulation through the asymmetric suppression of rotation around the axis of the prochiral biphenyl moiety. Nanospace: Self-assembled boronic ester cavitand capsules (see scheme) show unique properties that depend on the characteristics of the bis(catechol) linkers.
