Porous organic polymers (POPs) have been considered as prominent adsorbents for volatile iodine. So far, both crystalline and amorphous POPs have accomplished excellent iodine capture capability. Considering the difficulty and challenges in preparing perfect crystalline POPs, more explorations into developing versatile amorphous POPs are needed. Herein, amorphous POPs based on the Schiff‐base reaction were designed and synthesized for volatile iodine removal. Four amorphous POPs products named as NDB‐H, NDB‐S, ADB‐HS, and ADB‐S obtained under different solvothermal conditions were investigated in terms of their morphologies, porosity, and their iodine enrichment performance in detail. It is noteworthy that excellent efficiency for removing iodine vapor was acquired for NDB‐S (≈425 wt %), ADB‐HS (≈345 wt %), and ADB‐S (≈342 wt %). Remarkably, NDB‐H exhibited an iodine capture capacity up to ≈443 wt %. Excellent reusability was obtained as well. Amorphous NDB‐H has accomplished an extremely high iodine capture performance, illustrating the great chance to exploit versatile amorphous POPs for iodine enrichment and removal based on Schiff‐base chemistry.

基于席夫碱化学的非晶态多孔有机聚合物可高效捕获碘

多孔有机聚合物（POPs）被认为是挥发性碘的主要吸附剂。到目前为止，晶体和非晶态POP均具有出色的碘捕获能力。考虑到制备完美的晶体POP的困难和挑战，需要对开发通用的无定形POP进行更多的探索。在此，设计并合成了基于席夫碱反应的非晶态POP，用于去除挥发性碘。四种无定形POP产品名为NDB‐H，NDB‐S，ADB‐HS和ADB‐S详细研究了在不同溶剂热条件下获得的产物的形貌，孔隙率和碘富集性能。值得注意的是，NDB‐S（≈425wt％），ADB‐HS（≈345wt％）和ADB‐S（≈342wt％）获得了优异的去除碘蒸气的效率。值得注意的是，NDB-H的碘捕获能力高达约443 wt％。还获得了极好的可重用性。非晶态NDB-H已实现了极高的碘捕获性能，这说明了基于席夫碱化学方法利用多功能非晶态POP进行碘富集和去除的巨大机会。
