TThe purpose of introducing hydroxyl groups into fullerenes is to improve the water solubility of fullerenes, but only when the number of hydroxyl groups reaches more than 20 can they have better water solubility. Fullerol is insoluble in acetone and methanol, but soluble in DMF. Chemical properties are similar to those of fullerene. When the number of hydroxyl groups is small, 1,3 dipolar cycloaddition reaction can also occur. Fullerol can strongly absorb free radicals, inhibit the toxicity of chemical poisons, resist radiation, ultraviolet light damage, protect heavy metal cells from damage, resist cell oxidation, resist bacterial infection and absorb free radicals, thus protecting cells from various damages. It can be widely used in nuclear magnetic resonance imaging, anti-HIV drugs, anti-cancer drugs, chemotherapy drugs, cosmetic additives, scientific research and many other fields
