The construction of porous organic polymer from 5,10,15,20-tetraphenylporphyrin (TPP) was described using one-pot Friedel-Crafts alkylation reaction. Au was simultaneously loaded on the porphyrin-based polymer denoted as Au/KAPs(DCM-TPP). This polymer-supported Au was fully characterized by many physicochemical methods. It was found to possess BET surface area of 796 m2 g−1, good thermal stability above 250 °C and Au nanoparticles with an average size of 8 nm. It was used as an efficient heterogeneous catalyst for alkyne hydration and alcohol oxidation in water. This Au catalyst exhibited excellent catalytic efficiency and recycling performance without loss of activity at least five times. A new strategy to synthesize polymer-supported Au nanoparticle catalyst was finally provided.

一锅法合成卟啉基聚合物负载的金纳米粒子作为炔烃水合和水中醇氧化的有效催化剂

使用一锅 Friedel-Crafts 烷基化反应描述了由 5,10,15,20-四苯基卟啉 (TPP) 构建多孔有机聚合物。Au同时负载在以Au/KAPs(DCM-TPP)表示的基于卟啉的聚合物上。这种聚合物负载的 Au 被许多物理化学方法完全表征。发现它具有 796 m2 g-1 的 BET 表面积,250 °C 以上的良好热稳定性和平均尺寸为 8 nm 的 Au 纳米粒子。它被用作炔烃水合和醇在水中氧化的有效多相催化剂。这种 Au 催化剂表现出优异的催化效率和回收性能,而活性至少不会损失 5 倍。最终提供了一种合成聚合物负载的金纳米颗粒催化剂的新策略。
