A SIFSIX-MOF constructed from a metalloligand yields enhanced stability for selective CO2 adsorption

A metalloligand(ML)-based SIFSIX MOF [Cu(ML) 2 (SiF 6 )] n (ML = Cu(pyac) 2 = bis[3-(4-pyridyl)pentane-2,4-dionato]copper( ii )) possesses one-dimensional (1D) channels with accessible Cu 2+ sites that provide superior CO 2 uptake and water vapor stability.
