Abstract
Photolysis of cyclic disulfides with single-walled carbon nanotubes led to a sidewall modification of the surface to introduce sulfur-containing functional groups, confirming by means of Raman, XPS, FT-IR, mass and UV–vis–NIR measurements. Subsequent treatment of sulfur-containing substituents modified SWNTs with gold nanoparticles gave an attachment of gold on the surface of SWNTs through thioalkylthiol linkage.
