We newly introduce positional isomeric structures at the defect sites of locally-functionalized single-walled carbon nanotubes (lf-SWNTs) showing unique near infrared photoluminescence (PL). The observed PL is significantly different from that of typical para-aryl modified lf-SWNTs; i.e., (i) an extraordinary PL wavelength shift of the meta-aryl modified lf-SWNTs, and (ii) remarkably red-shifted PL from the ortho-aryl modified lf-SWNTs are revealed.
我们在具有独特近红外光致发光（PL）的局部功能化单壁碳纳米管（lf-SWNTs）的缺陷位点处新引入了位置异构结构。观察到的PL与典型的对芳基修饰的lf-SWNTs的PL有显著不同；即，（i）间芳基修饰的lf-SWNTs出现了异常的PL波长位移，以及（ii）邻芳基修饰的lf-SWNTs的PL显著红移。
