N2 - Poly(N-isopropylacrylamide) (PNIPAM) oligomer containing one adamantyl (AD) and two β-cyclodextrin (β-CD) moieties at the chain terminals, AD-PNIPAM-(β-CD)2, was synthesized by atom transfer radical polymerization (ATRP) and successive click reactions. In aqueous solution, AD-PNIPAM-(β-CD)2 spontaneously forms supramolecular thermoresponsive hyperbranched polymers via molecular recognition between AD and β-CD moieties. To the best of our knowledge, this work represents the first report of the construction of supramolecular thermoresponsive hyperbranched polymers from well-defined polymeric AB2 building units.
