Two unprecedented isomeric macrocycles, a tubular belt and a M?bius 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 M?bius 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.
