We report structural characterization of a new member of m‐phenylene ethynylene ring family. This shape‐persistent macrocycle also co‐crystallizes with hexafluoro‐, 1,2,4,5‐tetrafluoro‐, 1,3,5‐trifluoro, and 1,4‐difluorobenzene. The four complexes are almost isostructural, and all show the fluoroarene included into the central cavity of the macrocycle. Characterized by multiple short CH⋅⋅⋅FC contacts
我们报告了间亚苯基亚乙炔基环家族的新成员的结构表征。这种形状持久的大环也与六氟,1,2,4,5-四氟,1,3,5-三氟和1,4-二氟苯共结晶。这四个复合物几乎是同构的,都显示出大环中心腔中包含的氟芳烃。由多个短C,其特征 H⋅⋅⋅F C触点,这些包合配合物进一步二聚化在固态成2 + 2的组件,其中两个大环化合物通过由60旋转它们的大的疏水基团相互拥抱°相对于彼此。
