Abstract:

The chemical manipulation of single walled carbon nanotubes (SWNTs), especially the side walls funtionalization, has been an area of fundamental interest. Single walled carbon nanotube has opened a Pandora’s box for new electronic devices nanoestructured. Additionally, selenium exhibits a unique combination of many properties as a relatively low meting point (~217°C), piezoelectricity, non-linear optical response and high reaction flexibility with a number of chemical compounds that enable the achievement of a broad class of compounds of selenium, as ZnSe and CdSe. In this context, the preparation of a new hybrid system employing one-dimensional selenium nanostructures (Se-1D) and carbon nanotubes can afford a very interesting system for technological applications. In a previous publication, we have prepared a new selenium-carbon nanocable, employing a carbanionic intermediate species. This allowed an effective linkage between selenium and carbon nanotube sidewall, affording a covalent bond between this components.
