有机碱催化炔-羟基 click 聚合制备可降解含磷氮笼杂化聚合物
Degradable Phosphorus–Nitrogen Cage-Containing Hybrid Polymers via Activated Alkyne-Hydroxyl Click Polymerization
AI 导读
研究报道了一种有机碱催化的羟基-炔 click 聚合路线，可在温和条件下高效合成一系列聚膦腙乙烯基醚酯，单体适用范围较广。所得材料热稳定性较高，Td 在 310 至 325 °C 之间，残炭率最高达 61%，表面润湿性可调。降解实验显示，引入磷氮笼显著加速了乙烯基醚主链的酸催化水解，而无笼的类似体系在动力学上仍受抑制。
推荐理由
原文用有机碱催化的炔-羟基 click 聚合在温和条件下快速合成含磷氮笼杂化聚合物，并给出热稳定性与酸水解加速的对比。
创新点
用有机碱催化的炔-羟基 click 聚合替代动力学慢、条件苛刻的 Staudinger 反应，实现磷氮笼杂化聚合物的快速模块化合成，并发现磷氮笼能主动加速乙烯基醚主链的酸水解。
