文摘

Two 2D wavy hexagonal hexahydroxyl cyclotricatechylene (CTC) based COFs, CTC-COF-2 and CTC-COF-3 were synthesized through solvothermal reaction. The bowl-shaped conformation caused CTC skeletons packed in a columnar manner with the same oriented units, thus forming an undulated structure. The gas adsorption properties of CTC-COFs were investigated, which show the potential application abilities in hydrogen storage of CTC-COFs. The introduction of pyrene into CTC-COF-3 makes it a potential semiconducting π-conjugated material.
