We report the first evidence of a controlled organic reaction inside a carbon nanotube. C120O fullerene dimers were inserted into SWNTs in 30% yield, indicating a large energetic barrier for encapsulation.A heated C60/C60O/SWNT mixture formed oligomers composed of up to five fullerenes inside SWNTs in 60% yield. Such oligomers should have a very large energetic barrier to encapsulation, indicating that C60 and C60O entered as monomers and reacted inside the nanotube via epoxide ring opening. Mechanisms of filling and oligomer formation are discussed.
