A SIFSIX-MOF constructed from a metalloligand yields enhanced stability for selective CO 2 adsorption

The first example of a metalloligand(ML)-based non-interpenetrated SIFSIX MOF [Cu(ML) (SiF )] (ML = Cu(pyac) = bis[3-(4-pyridyl)pentane-2,4-dionato]copper(II)) exhibits one-dimensional pore channels decorated with accessible Cu sites that provide superior water vapor stability and CO selectivity over CH . similar materials constructed from non-metal containing organic ligands.
