Abstract
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.
