A Linear-Hyperbranched Supramolecular Amphiphile and Its Self-Assembly into Vesicles with Great Ductility

Abstract

A linear-hyperbranched supramolecular amphiphile was synthesized through the noncovalent coupling of adamantane-functionalized long alkyl chain (AD-C(n), n = 12, 18, 30) and hyperbranched polyglycerol grafted from β-cyclodextrin (CD-g-HPG) by the specific AD/CD host-guest interactions. The obtained supramolecular C(n)-b-HPGs self-assembled into unilamellar vesicles with great ductility that could be disassembled readily under a competitive host of β-CD.
