Significance
Functionalization of carbon nanotubes (CNTs) is one of the hot topics in nanoscience today, because it can offer the chances of tailoring their physical and chemical properties. Herein, a new functionalization method of single-walled carbon nanotube (SWCNT) through a cycloaddition of arynes, generated in situ by modified classical methods, onto the sidewall of SWCNT to give cycloadducts 1a and 1b is described. Characterization of the functionalized SWCNTs using Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), UV/Vis/NIR and FT-IR techniques supports the addition of arynes onto the sidewall of SWCNT.
