Radioactive iodine in nuclear waste would be harmful to nature and human health. The design of adsorbents for iodine capture with high efficiency still remains a challenge. Herein, two highly conjugated two-dimensional covalent organic frameworks (TFPB-BPTA-COF and TFPB-PyTTA-COF) have been successfully constructed. Both COFs possess high porosity, stability, and a high π-conjugated framework. Impressively, TFPB-PyTTA-COF exhibits an excellent iodine uptake value of up to 5.6 g g , which is superior to most reported COF-based adsorbents for iodine capture.
核废料中的放射性碘对自然和人类健康有害。设计高效捕获碘的吸附剂仍然是一个挑战。在此，成功构建了两种高共轭二维共价有机框架（TFPB-BPTA-COF 和 TFPB-PyTTA-COF）。这两种 COF 都具有高孔隙率、稳定性和高π共轭骨架。令人印象深刻的是，TFPB-PyTTA-COF 表现出高达 5.6 g/g 的优异碘吸附值，优于大多数报道的用于碘捕获的基于 COF 的吸附剂。
