The first synthesis of a conjugated hybrid of C60-fullerene and a single-wall carbon nanotube

The first synthesis of a conjugated hybrid Of C-60-fullerene and a single-wall carbon nanotube (SWCNT) is reported. The new nano-hybrid material has been prepared by amidation of acid functionalized SWCNTs by an amine functionalized-fullerene derivative. The formation of this new nanomaterial was demonstrated by high resolution TEM, attenuated total reflectance/FTIR and Raman spectroscopy. Acid hydrolysis of the new material produced carboxylic-SWCNTs and the recovery of the aminofullerene derivative as complementary evidence of their covalent link. This new SWCNT-fullerene material may be of interest in optoelectronic applications. (c) 2007 Elsevier Ltd. All rights reserved.
