Abstract: Herein, two new classes of macrocycliccompounds, terphen[n]arenes (TPns) (n=3–6) and quaterphen[n]arenes(QPns) (n=3–6), were designed and synthesized by a one‐stepcondensation reaction in relatively high yields. They comprise 2,2′′‐dimethoxyterphenyl and 2,2′′′‐dimethoxy quaterphenyl monomers, respectively,linked by methylene bridges. Given their long and rigid monomers, TPnsand QPns have much larger cavities and better self‐assemblyproperties than classic macrocycles. More interestingly, the cyclic pentamersand hexamers TP5, TP6, QP5, and QP6 formed supramolecular organogels, whichwere composed of interwoven fibers, nanosheets, or entangled macropore networksformed by multiple face‐to‐face and edge‐to‐faceπ⋅⋅⋅π stacking interactions. The xerogel materialseffectively captured volatile iodine, not only in aqueous media but also in thegaseous state, and could be recycled multiple times without obvious loss inperformance.
