Highly selective separation of toluene/methylcyclohexane based on pagoda[5]arene nonporous adaptive crystals

Highly selective separation of toluene (Tol) over methylcyclohexane (MCH) has been achieved by utilizing nonporous adaptive crystals of pagoda[5]arene P5. Specifically, P5 demonstrates not only superior binding capability for Tol in solution, but also excellent selectivity for separating Tol from an equivolume Tol/MCH mixture with a high purity of 98.8%. Herein the selective separation of toluene/methylcyclohexane based on pagoda[5]arene nonporous adaptive crystals is investigated.
