Abstract A novel phosphazene superbase (P1) organocatalyst heterogenized on a Porous Polymeric Aromatic Framework (PPAF) based on an adamantine node catalyzed metal-free ring-opening polymerization (ROP) of lactones to yield polyesters, showing a 7.7-fold increase in the turnover number for δ-valerolactone (δ-VL) and 3.3-fold increase in the case of e-caprolactone (e-CL) as comparing with its soluble counterpart. The heterogeneous catalyst can be reused until four times without loss of activity.

通过高效的多相磷腈 (P1)-多孔聚合物芳香骨架催化内酯的开环聚合合成聚酯

摘要 一种新型磷腈超强碱 (P1) 有机催化剂在基于金刚烷节点催化的内酯无金属开环聚合 (ROP) 的多孔聚合芳烃骨架 (PPAF) 上异质化,以产生聚酯,其营业额增加了 7.7 倍δ-戊内酯 (δ-VL) 的数量增加,ε-己内酯 (e-CL) 与其可溶性对应物相比增加了 3.3 倍。多相催化剂可以重复使用四次而不会损失活性。
