Self-Assembly of a Cavitand-Based Capsule by Dynamic Boronic Ester Formation

Be my guest: Two molecules of a cavitand tetraboronic acid and four molecules of a bis(catechol) linker quantitatively assemble into a capsule (see picture for two views), with highly selective guest‐recognition, by dynamic boronic ester formation. The on/off control of capsule formation with guest...

Summary:Be my guest: Two molecules of a cavitand tetraboronic acid and four molecules of a bis(catechol) linker quantitatively assemble into a capsule (see picture for two views), with highly selective guest‐recognition, by dynamic boronic ester formation. The on/off control of capsule formation with guest encapsulation is achieved by removal/addition of methanol.
