Supramolecular Assembly Based on the Novel Sail-Boat-Shaped Self-Complexes

Owing to the unique macrocyclic-cavity structure of crown ether and the capability of complexing with guest molecules, our group successfully designed and synthesized a novel Sailboat-Shaped self-complex by using intramolecular hydrogen bonds, which are able to switch its configuration during the different pH value. Furthermore, a novel catenane which based on the sailboat-shaped self-complex was obtained by using intermolecular charge transfer interaction and through the template- directed method, and its structure was identified by H-1 NMR, C-13 NMR, HRMS and H-1-H-1 NOESY. It is hoped that it can be successfully controlled by the pH value conversion.
