Abstract

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.
