研究了单壁碳纳米管的两步烷基化反应。用可见-近红外光谱仪、拉曼光谱仪、扫描电镜和热重分析仪对功能化单壁碳纳米管进行了表征。SWNT与烷基锂随后与烷基卤化物的这种一锅烷基化可用于SWNT的侧壁官能化。该反应对单壁碳纳米管的功能化程度有显著的取代基效应。单壁碳纳米管侧壁上的功能化程度可能通过取代基效应影响单壁碳纳米管侧壁上的特性。
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.
