Covalent organic frameworks (COFs) can be developed for molecular confinement and separation. However, their proximate π stacks limit the interlayer distance to be only 3–6 Å, which is too small for guests to enter. As a result, COFs block access to the x–y space and limit guest entry/exit strictly...
