在 C60 的甲苯或二氯苯溶液中通入 O3 ,通过改变 O3 的吸收量及反应时间可得到两种氧化产物 .一种产物在有机溶剂及水中均不溶 ,但经碱性水解后得到水溶性产物 ,其红外光谱与 C60 羟基化合物相似 ;在长时间通 O3 条件下 ,得到水溶性的 C60 氧化产物 .用变温红外光谱、XPS、元素分析、热谱和质谱研究了氧化产物的可能结构 ,发现生成的 C60 氧化产物对热不稳定 ,随着温度升高 ,有 CO2 ,CO和 H2 O放出
In the C60 toluene or dichlorobenzene solution through the O3, by changing the O3 absorption and reaction time can be two kinds of oxidation products.A product of both organic solvents and water are insoluble, but after alkaline hydrolysis obtained water-soluble The infrared spectrum of the product was similar to that of the C60 hydroxyl compound, and the water-soluble C60 oxidation product was obtained under the condition of O3 for a long time.The possible structure of the oxidation product was studied by TEM, XPS, elemental analysis, thermal and mass spectra The resulting C60 oxidation products are unstable to heat, with increasing CO 2, CO and H 2 O emissions
