Through a one‐pot Friedel–Crafts polymerization method, a series of 8‐hydroxyquinoline‐based polymers with excellent light capturing ability is synthesized to support palladium for light‐driven Suzuki–Miyaura reactions (SMRs). The results of X‐ray powder diffractometer and transmission electron microscopy analyses suggest that the 8‐hydroxyquinoline‐based polymers are amorphous in structure and irregular in morphology. According to the data of thermogravimetric analysis and Brunauer‐Emmett‐Teller gas absorption, they are thermally stable up to 340 °C and are large in specific surface area. With palladium anchored securely on the 8‐hydroxyquinoline units of the polymer skeleton, the obtained photocatalysts exhibit excellent activity and reusability in SMRs under blue‐light irradiation.

基于8-羟基喹啉的聚合物上钯的光催化Suzuki-Miyaura偶联反应

通过单锅Friedel-Crafts聚合方法，合成了一系列具有出色光捕获能力的8-羟基喹啉基聚合物，以支持钯用于光驱动Suzuki-Miyaura反应（SMR）。X射线粉末衍射仪和透射电子显微镜分析的结果表明，基于8-羟基喹啉的聚合物在结构上是无定形的，在形态上是不规则的。根据热重分析和Brunauer-Emmett-Teller气体吸收的数据，它们在高达340°C的温度下都是热稳定的，并且比表面积很大。钯牢固地锚固在聚合物骨架的8-羟基喹啉单元上，所获得的光催化剂在蓝光照射下的SMR中表现出出色的活性和可重复使用性。
