Naked metallic and semiconducting single-walled carbon nanotubes (SWNTs) were dissolved in organic solutions by derivatization with thionychloride and octadecylamine. Both ionic (charge transfer) and covalent solution-phase chemistry with concomitant modulation of the SWNT band structure were demonstrated. Solution-phase near-infrared spectroscopy was used to study the effects of chemical modifications on the band gaps of the SWNTs. Reaction of soluble SWNTs with dichlorocarbene led to functionalization of the nanotube walls.
通过用亚硫酰氯和十八烷基胺衍生化，将裸金属和半导体单壁碳纳米管（SWNTs）溶解于有机溶液中。展示了离子（电荷转移）和共价溶液相化学以及伴随的SWNT能带结构调制。利用溶液相近红外光谱研究化学修饰对SWNTs带隙的影响。可溶性SWNTs与二氯卡宾的反应导致纳米管壁的功能化。
