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.
通过一步环化反应构建了两个前所未有的异构体大环，一个管状带和一个莫比乌斯带，它们带有噻蒽连接点。这两种结构均通过核磁共振光谱、质谱和单晶X射线衍射进行了全面表征。一项络合研究表明，管状带是缺电子客体的容器。莫比乌斯带表现出扭转迁移动力学，其可由钠离子调节。它们的简便合成、独特结构和多样的主客体化学丰富了带状化学。
