Metallofullerene
Definition and meaning of Metallofullerene in chemistry.
A metallofullerene is a type of fullerene molecule where one or more metal atoms are trapped inside the hollow carbon cage. They are also known as endohedral metallofullerenes and represent a unique class of hybrid materials.
In more detail
These compounds combine the properties of the encapsulated metal atom with the protective carbon shell of the fullerene cage. The carbon cage acts as a shield, stabilizing reactive metal species that would otherwise degrade rapidly in ambient conditions. Metallofullerenes are widely studied for their potential applications in medicine, particularly as MRI contrast agents, and in materials science for their unique electronic and magnetic properties. The interior space of the fullerene provides a highly isolated environment for the metal.

Frequently asked questions
What does the '@' symbol mean in these formulas?
The '@' symbol indicates that the atoms listed before it are physically trapped inside the cage of the atoms listed after it, rather than being chemically bonded to the outside.
