Abstract:

Endohedral metallofullerene Gd@C2n were synthesized with high-yield using the carbon-arc discharge method of activating the Gd2O3-containing graphite anode in situ and back-burning technique. A series of Cd@C(2n) for 2n from 70 to 96 were effectively extracted by toluene at high-temperature and under high-pressure condition. Gd@C(82), Gd@C(74) were considered to be fairly stable and soluble metallofullerene species.

Key words: Fullerene, Metallofullerenes, Gd@ C2n
