由于具有挑战性的合成组成不同的支化共聚物，结构代表了聚合物设计中未充分利用但有前途的控制元素。本文报道了通过开环易位聚合一锅法合成杂臂支化聚合物。在这项工作中，我们接枝和从遥爪聚（3-己基噻吩），这是通过肟点击化学封端，使用不同的双烯单体。在溶液和固体状态下研究了所得杂臂H形共轭聚合物的自组装。制备显示pH可切换的较低临界溶液温度和荧光的双重刺激响应性杂臂聚合物。
Architecture represents an underutilized yet promising control element in polymer design due to the challenging synthesis of compositionally varied branched copolymers. We report the one-pot synthesis of miktoarm branched polymers by ring-opening metathesis polymerization. In this work, we graft to and from telechelic poly(3-hexylthiophene), which is end-capped by oxime click chemistry, using various norbornene monomers. The self-assembly of the resulting miktoarm H-shaped conjugated polymers is studied in solution and in the solid state. A dual stimuli-responsive miktoarm polymer is prepared which displays pH-switchable lower critical solution temperature and fluorescence.
