Inside Back Cover: First Encapsulation of Organometallic Single‐Molecule Magnet into Single‐Walled Carbon Nanotubes (Angew. Chem. Int. Ed. 22/2025)

Dysprosium cyclopentadienide is a single‐molecule magnet. Like other organometallic compounds, it is highly sensitive to moisture and oxygen. Encapsulating it in single‐walled carbon nanotubes protects it from decomposition by environmental water or oxygen and maintains its magnetic character, as reported by Haitao Zhang, Yoji Horii, Masahiro Yamashita et al. in their Research Article ( e202503979 ).
