ABSTRACT
Endohedral fullerenes have attracted special interest since the
first proposal of their existence in 1985. They are a new type
of carbon cluster containing one or more atoms inside the hol-
low fullerene cage. Particularly, endohedral metallofullerenes have
attracted broad attention because of their properties resulting
from an intramolecular metal-fullerene cage interaction. Their
recent production and isolation has enabled detailed characteriza-
tions of metallofullerenes’ chemical reactions. Endohedral metallo-
fullerenes’ unique chemical properties and structures have been
revealed through studies of functionalization.
