A two-step alkylation of single-walled carbon nanotubes was investigated. The functionalized SWNTs were characterized with vis-NIR and Raman spectrometers, scanning electron microscope, and thermogravimetric analysis. This one-pot alkylation of SWNTs with alkyllithium followed by alkyl halide is useful for the sidewall functionalization of SWNTs. This reaction shows significant substituent effects on the degree of functionalization of SWNTs. The degree of functionalization on SWNTs sidewall upon SWNTs may influence their characteristic properties on SWNTs sidewall by the substituent effects.
研究了单壁碳纳米管的两步烷基化反应。用可见-近红外和拉曼光谱仪、扫描电子显微镜和热重分析对功能化的 SWNTs 进行了表征。这种用烷基锂对 SWNTs 进行的一锅烷基化反应，然后再用卤代烷烃进行烷基化反应，对于 SWNTs 的侧壁功能化是有用的。这种反应对 SWNTs 的官能化程度表现出显著的取代基效应。通过取代基效应，SWNTs 侧壁上的官能化程度可能会影响 SWNTs 侧壁上的特征性质。
