| Abstract: | A simple water-soluble naphthalenedithiol building block is converted quantitatively into a series of octameric 2]-catenanes, composed of two interlocked molecular squares. When this mixture is re-equilibrated in the presence of an adamantyl ammonium guest, the catenanes disassemble into their macrocyclic components that bind the guest with nanomolar affinity in water. |
