摘要
A CpCo group was introduced in a cubic cage to generate a sphere‐like force surface, thus dividing the cubic cage into two parts. Gas molecules have to pass the sphere‐like force surface twice, which increases the interaction probability between gas and framework. Based on the high selectivity of the CpCo group, high‐purity ethylene is obtained from an acetylene/ethylene/ethane ternary mixture, as reported by Daofeng Sun et al. in their Research Article on page 11350.
