Abstract 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 −1 , which is superior to most reported COF‐based adsorbents for iodine capture.
