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 318 K, 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 that π-complexation contributes dominantly to the high ethylene-ethane adsorption selectivity.
将开放金属位点（OMS）与π络合相结合引入金属有机框架（MOF），已在318K时实现了非常高的乙烯-乙烷吸附选择性，如MIL-101-Cr-SO3Ag的情况所示。通过原位红外光谱研究和计算计算，对MIL-101-Cr-SO3Ag中来自OMS和π络合的与乙烯的相互作用进行了研究，结果表明π络合对高乙烯-乙烷吸附选择性起主要作用。
