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.
聚(N-异丙基丙烯酰胺)(PNIPAM)低聚物在链末端含有一个金刚烷基(AD)和两个β-环糊精(β-CD)部分,AD-PNIPAM-(β-CD)(2)通过原子转移自由基聚合(ATRP)和连续点击反应合成。在水溶液中,AD-PNIPAM-(β-CD)(2)通过 AD 和β-CD 部分之间的分子识别自发形成超分子温度响应超支化聚合物。据我们所知,这项工作代表了首次从结构明确的聚合物 AB2 构建单元构建超分子温度响应超支化聚合物的报道。
