Template-directed construction of conformational supramolecular isomers for bilayer porous metal-organic frameworks with distinct gas sorption behaviors

A pair of supramolecular isomers of Co(II)-based metal-organic frameworks can be directionally constructed in virtue of solvent templates, which show diverse bilayer networks and lattice packing with the same Co-3 SBUs and organic linkers. The two porous materials show distinct gas sorption behaviors at different temperatures, especially their CO2 sorption selectivity.
