In this study, a new macrocycle with nanometer-sized cavities was successfully designed and synthesized, showing excellent adsorption capacity for benzene. The compound can effectively separate benzene from a mixture of benzene and cyclo-hexane, with high purity and easy recycling.
In this work, we design and synthesize a new macrocycle, phenanthrene[2]arene 1, with nanometer-sized cavities in high yield. The nonporous adaptive crystals of phenanthrene[2]arene exhibit excellent benzene (PhH) adsorption capacity, and one host molecule can at maximum adsorb five PhH molecules. Moreover, activated crystals of 1 are able to separate PhH from an equimolar mixture of PhH and cyclo-hexane (Cy) and the purity of the PhH can reach 98.4% under mild and user-friendly conditions. In addition, fast adsorption, high loading ratios, high purity, and easy recycling are achieved with the present system for the separation of PhH and Cy, which is promising for practical applications.
