采用局部化学官能化方法对单壁碳纳米管（SWNTs）进行缺陷掺杂，以获得近红外光致发光（NIR PL）性能。我们报道了通过与芳醛基团相连的局部掺杂位点的化学反应，SWNTs的近红外PL的多步波长移动。基于亚胺化学对掺杂的单壁碳纳米管的PL波长进行调制。这涉及亚胺与添加芳胺形成醛基团，亚胺解离反应，亚胺中结合芳胺的交换反应，以及亚胺基使用亚磷酸二异丙酯的Kabachnik-Fields反应。利用掺杂位点作为局部化学反应平台，可以开发碳纳米管和相关纳米材料的多种分子驱动功能。
Local chemical functionalization is used for defect doping of single‐walled carbon nanotubes (SWNTs), to develop near‐infrared photoluminescence (NIR PL) properties. We report the multistep wavelength shifting of the NIR PL of SWNTs through chemical reactions at local doped sites tethered to an arylaldehyde group. The PL wavelength of the doped SWNTs is modulated based on imine chemistry. This involves the imine formation of aldehyde groups with added arylamines, imine dissociation reaction, exchange reaction of bound arylamines in the imine, and the Kabachnik–Fields reaction of imine groups using diisopropyl phosphite. Using doped sites as a localized chemical reaction platform can exploit the versatile molecularly driven functionality of carbon nanotubes and related nanomaterials.
