The synthesis of highly microporous, epoxy-functionalized porous organic polymers (ep-POPs) by a one-pot, catalyst-free Diels-Alder cycloaddition polymerization is reported. The high oxygen content of ep-POPs offer efficient hydrogen-bonding sites for water molecules, thus leading to high water-uptake capacities up to 39.2-42.4 wt % under a wide temperature range of 5-45 °C, which covers the span of climatic conditions and manufacturing applications in which such materials might be used. Importantly, ep-POPs demonstrated regeneration temperatures as low as 55 °C, as well as excellent water stability, recyclability, and high specific surface areas up to 852 m g .
本文报道了一种通过一锅无催化剂 Diels-Alder 环加成聚合制备高微孔、环氧官能化多孔有机聚合物（ep-POPs）的方法。ep-POPs 的高氧含量为水分子提供了有效的氢键结合位点，因此在 5-45°C 的较宽温度范围内具有高达 39.2-42.4wt%的高吸水性，这涵盖了气候条件和制造应用的范围，这些材料可能在其中得到应用。重要的是，ep-POPs 的再生温度低至 55°C，具有出色的水稳定性、可回收性和高达 852m2/g 的比表面积。
