Fullerene oxides were synthesized by fullerene ($C_{70}$) and several amine N-oxides such as 3-picoline N-oxide, pyridine N-oxide hydrate, quinoline N-oxide, and isoquinoline N-oxide under ultrasonic condition at $25{\sim}43^{\circ}C$. The reactivity of fullerene ($C_{70}$) with various amine N-oxides undo, ultrasonic irradiation showed the same in all of the proceeding experiments; 3-picoline N-oxide : pyridine N-oxide hydrate : quinoline N-oxide : isoquinoline N-oxide. The MALDI-TOF MS, UV-vis spectrophotometer and HPLC analysis confirmed that the products of fullerene oxidation are [$C_{70}(O)n$] (n=1).
