Abstract

Control over chemical functionalization is a crucial point in the field of nanotechnology. Herein, wepresent the covalent functionalization of several carbon nanoforms (single-walled carbon nanotubes,double-walled carbon nanotubes, multi-walled carbon nanotubes and carbon nanohorns) by means ofdiphenyl dichalcogenides. These ones show different reactivity to the nanomaterials and are able tomodify their electronic properties depending on the electronegativity of the functionalizing heteroatom.Theoretical calculations were also performed to support the experimental results. All the modifiedstructured nanocarbons were thoroughly characterized by TGA Raman, XPS, UV/Vis/nIR, IR and TEMtechniques. Our findings propose a simple approach to functionalize carbon nanomaterials and, in themeantime, to tune their electronic properties.
