Abstract

The introduction of the combination of open metal site (OMS) and π-complexation into MOF has led to very high ethylene/ethane adsorption selectivity at 318K, as illustrated in the context of MIL-101-Cr-SO3Ag. The interactions with ethylene from both OMS and π-complexation in MIL-101-Cr-SO3Ag have been investigated by in situ IR spectroscopic studies and computational calculations, which suggest π-complexation contributes dominantly to the high ethylene/ethane adsorption selectivity.
