【摘要】 采用γ-氨丙基-三乙氧基硅烷作为偶联剂,将伯胺基引入到硅胶上,随后让C60与伯胺基反应,合成了C60-γ-氨丙基硅胶.利用元素分析法和Esko等描述的游离伯胺基含量测定方法,分别测得每1g硅胶中C60的键合量为1.19×10-5mol和1.09×10-5mol.更多还原

【Abstract】 C60γaminopropylsilylbonded silica was synthesized by chemical attachment of γaminopropylsilyl to silica, followed by the reaction of C60 with alkylamine. Using elemental analysis and the method for measuring the amounts of alkylamine described by Esko et al., the content of bonded C60 was determined to be 119×10-5 mol and 109×10-5 mol in per gram silica, respectively.更多还原
