摘　　要：Polyhaloalkanes are broadly useful yet environmentally harmful stock chemicals,therefore the development of adsorbent materials with capacity and selectivity for polyhaloalkane vapors is highly desirable.Here we report a novel macrocycle WreathArene,a fluorinated C;-symmetrical [1;]-paracyclophane.In the crysalline state,WreathArene features guest-adaptive polymorphism for polyhaloalkanes including chloroform,tribromomethane,1,1,2-trichloroethane,and 1,2-dibromoethane.Non-covalent C-halogen…πinteractions are observed in all of these host-guest structures.Based on these properties,the activated WreathArene crystals can be utilized as a selective and recyclable adsorbent for polyhaloalkane vapors with excellent capacity under user-friendly conditions.
