Covalent organic frameworks (COFs) are penetrated with uniform and ordered nanopores, implying their great potential in mol./ion separations As an imine-linked, stable COF, TpPa-1 is receiving tremendous interest for mol. sieving membranes. Theor., atomically thin TpPa-1 monolayers exhibit extremely high water permeance but unfortunately no rejection to ions because of its large pore size (∼1.58 nm). The COF monolayers tend to stack to form laminated multi-layers, but how this stacking influences water transport and ion rejections remains unknown. Herein, we investigate the transport behavior of water and salt ions through multi-layered TpPa-1 COFs by nonequilibrium mol. dynamics simulations. By analyzing both the interfacial and interior resistance for water transport, we reveal that with rising stacking number of COF multi-layers exhibit increasing ion rejections at the expense of water permeance. More importantly, stacking in the offset eclipsed fashion significantly reduces the equivalent pore size of COF multi-layers to 0.89 nm, and ion rejection is correspondingly increased. Remarkably, 25 COF monolayers stacked in this fashion give 100% MgCl2 rejection, whereas water permeance remains 1 to 2 orders of magnitude higher than that of com. nanofiltration membranes. This work demonstrates the rational design of fast membranes for desalination by tailoring stacking number and fashion of the COF monolayers. In the experiment, the researchers used many compounds, for example, 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Quality Control of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde)
