ABSTRACT
Conventional endohedral metallofullerenes (EMFs) refer to these species discovered at the early stage of research, mainly pointing to mono-EMF and di-EMFs. Novel EMFs are these compounds containing a metallic cluster of various kinds which were discovered within the past 10 to 12 years. Because the internal metallic species exert fundamental influences on the cage carbons, the inherent properties of conventional EMFs differ significantly from those of cluster EMFs, especially in terms of chemical properties. Accordingly, we address the chemistry of EMFs in accordance with the type and composition of the internal metallic species.
