通过一步环化反应，构建了两个前所未有的同分异构大环，一个管状带和一个莫比乌斯带，具有噻蒽关节。这两种结构都通过NMR光谱、质谱和单晶X射线衍射进行了充分表征。络合研究表明，管状带是一个容器的电子缺乏客人。莫比乌斯带具有扭曲迁移动力学，可以通过钠离子进行调节。它们简单的合成、独特的结构和多样的主客体化学性质丰富了带化学。
Two unprecedented isomeric macrocycles, a tubular belt and a Möbius strip, with thianthrene joints have been constructed through a one-step cyclization reaction. Both structures are fully characterized by NMR spectroscopy, mass spectrometry, and single-crystal X-ray diffraction. A complexation study reveals that the tubular belt is a container for electron deficient guests. The Möbius strip exhibits twist-migration dynamics, which can be regulated by a sodium ion. Their facile synthesis, unique structure, and diverse host-guest chemistry enrich the belt chemistry.
