Abstract
New hybrid materials were synthesized by functionalizing single wall carbon nanotubes (SWCNTs) with different semiconducting species. Vinyl quinoline monomers bearing electron accepting groups or even its ruthenium complex were used as organic semiconductors. UV–vis–NIR absorption spectroscopy, X-ray photoelectron spectroscopy and thermogravimetric analysis were used in order to qualify the resulted materials. Optical characteristics were studied by photoluminescence spectroscopy in neutral and acidic media. The electronic structure of the valence band and the surface electronic properties of the materials in the form of thin films developed on Si substrates were studied by ultraviolet photoelectron spectroscopy. Raman spectroscopy revealed the charge transfer mechanism between the polymer and the carbon nanotube while the recorded Raman resonance profiles showed significant changes in the transition energies and the widths of the resonance windows due to chemical modification of SWCNTs.
