Two 2-dimensional covalent organic frameworks (COFs; TJNU-203 and TJNU-204) with high crystallinity and large specific surface area are rationally fabricated using a three-connected distorted building block and linear linkers. The two COFs show high iodine uptake (5.885 g g-1 for TJNU-203 and 5.335 g g-1 for TJNU-204) on account of physical-chemical adsorption, which make them one among the best porous materials for iodine adsorption.
使用三连接扭曲构建块和线性连接体合理制备了两种具有高结晶度和大比表面积的二维共价有机框架（COF；TJNU - 203和TJNU - 204）。由于物理化学吸附，这两种COF表现出高碘吸附量（TJNU - 203为5.885 g g-1，TJNU - 204为5.335 g g-1），这使它们成为碘吸附性能最佳的多孔材料之一。
