Location of the Yttrium Atom in Y@C_(82) and Its Influence on the Reactivity of Cage Carbons

摘要

Endohedral metallofullerenes (EMFs) are generated by encapsulation of metal atom(s) or metallic clusters inside the hollow cavities of fullerenes. Because of the electron transfer from the encaged metallic species to the carbon cage, this new class of hybrid molecules has shown unique structures, novel properties, and promising applications in biology, medicine, and electronics. Although the cavities of fullerenes can contain as many as six atoms, monometallofullerenes-EMFs with only one metal atom inside-are viewed to be the simplest examples for unraveling the structures and properties of EMFs.
