Endohedral Metallofullerenes

After our long-term research we have unique possibility to produce the "gram" amount of Endohedral Metallofullerenes ( EMF ).

Our method makes it possible a "gram" isolation of EMF, free from empty Fullerenes.

This eliminates the difficulties associated with the EMF isolation.

We produce the EMF in the Anionic form that is confirmed by ESI - MS method.

The "gram" amount production open the broad possibility for extended scientific researches and for future application these new products, especially for unlimited possibility for synthesis of EMF derivatives, including water soluble.

The Anionic EMFs are stable and we can suplly these compounds as powder.

At present we produce 80-90% enriched EMF : Gd@C₈₂, La@C₈₂ which according to recent publication ( * ) can be easily isolated through the use reduction in the extraction process and different solubilities between neutral empty fullerenes and Endohedral Metallofullerene Anions.
