synthesized by a one‐step condensation reaction in relatively high yields. They comprise 2,2′′‐dimethoxy terphenyl and 2,2′′′‐dimethoxy quaterphenyl monomers, respectively, linked by methylene bridges. Given their long and rigid monomers, TPns and QPns have much larger cavities and better self‐assembly properties than classic macrocycles. More interestingly, the cyclic pentamers and hexamers TP5, TP6, QP5, and
在这里,设计并合成了两类新的大环化合物,即萜烯[ n ]芳烃(TP n s)(n = 3–6)和季戊酚[ n ]芳烃(QP n s)(n = 3-6)。一步式缩合反应,产率较高。它们分别包含通过亚甲基桥连接的2,2''-二甲氧基三联苯基和2,2'''-二甲氧基四联苯基单体。考虑到它们长而刚性的单体,TP n s和QP n与经典的宏周期相比,它们具有更大的空腔和更好的自组装特性。更有趣的是,环状五聚体和六聚体TP5,TP6,QP5和QP6形成了超分子有机凝胶,该有机凝胶由交织的纤维,纳米片或由多个面对面和边对面π⋅⋅形成的缠结大孔网络组成⋅π堆叠相互作用。干凝胶材料不仅在水性介质中而且在气态中都有效地捕获了挥发性碘,并且可以多次回收而不会明显降低性能。
