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 AB 2 building units.
