Abstract:
A water-soluble fullerene [C(70)] is prepared with fullerene [C(70)] and a mixture of concd. sulfuric acid (H(2)SO(4)) and concd. nitric acid (HNO(3)) at the ratio (v/v) of 3:1 under ultrasonic irradiation at 25-43 degrees C. The MALDI-TOF-MS spectra confirmed that the product of a water-soluble fullerene compound was C(70).
