Selective SF₆ adsorption and separation in pyrene-based metal-organic frameworks

• Anthropogenic greenhouse gas emission poses a serious threat to our environment and it is therefore of utmost importance that efficient systems are developed to mitigate these issues. SF6, in particular, has attracted more attention in recent years due to its global warming potential which severely exceeds that of CO2. In this study we present the SF6 sorption properties of four highly porous 1,3,6,8-tetrakis(4-carboxyphenyl)pyrene-based (TBAPy4-) metal-organic frameworks containing either ytterbium(III), thulium(III), cerium(III), vanadium(IV), gallium(III), or hafnium(IV). These MOFs can be synthesized with high crystallinity within 24 h and were found to have good SF6 uptakes due to their suitable pore size.
