Synthesis and Characterization of Lu3N@C80O

Oxygenated hollow cage fullerenes have been intensively studied due to their applications in biomedicine in recent years. Clusterfullerenes have become a focus of endohedral fullerene researches for their exceptionally high yield and thermal stabilities. However, oxide derivatives of clusterfullerene remain unexplored to date. Herein, we present the photochemical synthesis of an oxide derivative of clusterfullerene, Lu₃N @C₈₀O , for the first time. The compound was characterized by matrix‐assisted laser desorption ionization time‐of‐flight mass spectrometry, UV –vis‐NIR , cyclic voltammetry, and FTIR spectroscopy. The results suggest that one oxygen atom bridges with the fullerene cage after the oxidation of Lu₃N @C₈₀ . Moreover, the oxidation has a major impact on the electrochemical behavior of Lu₃N @C₈₀ .
