#COFs #H2O #sorption During water sorption, capillary pressure in 2D COF nanochannels can be massive enough to deform or even destroy their crystal structures @J_A_C_S
pubs.acs.org
Two-dimensional covalent organic frameworks (2D COFs) have been widely applied in liquid environments, where capillary forces inevitably arise when the well-defined nanochannels of 2D COFs contact...

#COFs #sensing The structural dynamics of 2D COFs is often associated with out-of-plane interlayer shifting. We demonstrate in-plane structural dynamics of 2D COFs featured by a pore breathing behavior
pubs.rsc.org
Two-dimensional (2D) covalent organic frameworks (COFs) are typically regarded as having rigid in-plane pores. In this study, we successfully synthesized a series of 2D COFs (NUS 126–128) character...

#editorial #gas_separation #CO2 Macrocyclic aromatic systems have been shown to selectively take up CO2 in the presence of water. Congratulations to @aicooper @NatureChemistry
nature.com
Nature Chemistry - The application of physisorption-based processes under humid conditions has long been hindered by the tendency of water to adsorb in preference to CO2. Now, macrocyclic aromatic...
