(Invited) Carbon Nanotubes-Fullerene Hybrids

Langa, Fernando

The combination of two carbon nanostructures in a single material, giving rise to new hybrids with improved mechanical, electrical, and thermal properties, has sparked a great interest in the last years.[1],[2],[3] Hybrids combining carbon nanotubes and fullerene derivatives have been described by endohedral,[4] supramolecular[5] and covalent[1] approaches, showing, in general, rather poor solubility in common solvents, which hampered the study of the resulting photophysical properties. In this regard, the synthesis of nanohybrids bearing long alkyl chains,[2]_^,[6]improve the dispersibility in organic solvents, rendering them excellent candidates for their application in the semiconducting materials field.

In this presentation, we will discuss our recent studies involving the synthesis of nanohybrids combining carbon nanotubes and C₆₀, as well as the new photophysical properties arising from the combination of both carbon nanomaterials.
