Abstract

A new and convenient method for covalent attachment of thioamide groups to the side-walls of carbon nanotubes (SWNT) via the Willgerodt–Kindler (WK) reaction is presented. Treating SWNTs with 4-acetylaniline and subsequently with morpholine as a secondary amine and sulfur leads to the thioamidation of SWNTs. This approach paves the way for a new chemical functionalization protocol to enhance the potential of SWNTs for further chemical reactions applicable in various fields.
