Abstract:
With the development of nuclear power, the removal of radionuclides is an important responsibility and task. Radioactive iodine, as one of the most radionuclide in nuclear wastes, its safe disposal is essential to ensure the sustainable development of the nuclear industry. Covalent organic framework materials are crystalline organic porous materials, which were constructed by covalent bonds. Because of their regular pore structure, large surface area and high chemical stability, covalent organic framework materials are selected as an ideal iodine capturing materials due to their structural cha

Abstract:
AbstractCovalent organic frameworks (COFs) are distinguished from other organic polymers by their crystallinity1–3, but it remains challenging to obtain robust, highly crystalline COFs because the framework-forming reactions are poorly reversible4,5. More reversible chemistry can improve crystallinity6–9, but this typically yields COFs with poor physicochemical stability and limited application scope5. Here we report a general and scalable protocol to prepare robust, highly crystalline imine COFs, based on an unexpected framework reconstruction. In contrast to standard approaches in which mono
