Epoxy‐functionalized porous organic polymers via diels‐alder cycloaddition reaction for atmospheric water capture

Byun, Yearin ; Coskun, Ali

In: Angewandte Chemie, 2018, p. -

We report on the synthesis of highly microporous, epoxy-functionalized porous organic polymers (ep-POPs) through one pot, catalyst-free Diels-Alder cycloaddition polymerization. The high oxygen content of ep-POPs offered efficient hydrogen bonding sites for water molecules, thus leading to high water uptake capacities, up to 39.2-42.4%, under a wide temperature range of 5-45oC, covering the...

    Summary
    We report on the synthesis of highly microporous, epoxy-functionalized porous organic polymers (ep-POPs) through one pot, catalyst-free Diels-Alder cycloaddition polymerization. The high oxygen content of ep-POPs offered efficient hydrogen bonding sites for water molecules, thus leading to high water uptake capacities, up to 39.2-42.4%, under a wide temperature range of 5-45oC, covering the climatic conditions and various manufacturing applications. Importantly, ep-POPs demonstrated regeneration temperatures as low as 55oC and excellent water stability, recyclability as well as high specific surface areas (up to 852 m2 g-1).
