| Summary: | The separation of chlorobenzene (<b>CB</b>) and chlorocyclohexane (<b>CCH</b>) using traditional industrial separation technologies (distillation, fractionation, and rectification) is a great challenge due to their close boiling points. Here, we report an innovative method for the separation of the mixture of <b>CB</b> and <b>CCH</b> by nonporous adaptive crystals (NACs) of perethylated pillar[6]arene (<b>EtP6</b>). NACs of <b>EtP6</b> (<b>EtP6</b><i>α</i>) can selectively adsorb <b>CCH</b> vapor from the vapor mixture of <b>CB</b> and <b>CCH</b> (<i>v</i>:<i>v</i> = 1:1) with a purity of 99.5%. Furthermore, <b>EtP6</b><i>α</i> can be recycled for five times without a significant loss of performance. |
