Photolysis of cyclic disulfides in the presence of carbon materials such as diamond films and single-walled carbon nanotubes led to a surface modification to introduce thioalkylthiol functional groups, confirming by means of Raman, X-ray photoelectron spectroscopy and mass spectrometer measurements. The results on the value of S/C ratio of sulfur-modified diamond films depends on irradiation time by monitoring with XPS. Through thioalkylthiol moieties, an attachment of gold nanoparticles using self-assembly process was performed on carbon materials surfaces.
