Abstract

Raman scattering is used to study the filling of single wall carbon nanotubes with C₆₀, C₅₉N

and anthracene. It is demonstrated how reversible opening and closing

of the tubes can be used to check on the success of the filling process.

In the case of C₅₉N, filling was performed from the gas phase from 1:1 mixture between C₆₀ and C₅₉N. Comparing the Raman spectra from the encapsulated mixture with the spectra from C₆₀ inside the tubes reveals that most of the molecules have reacted to form either the dimer (C₅₉N)₂ or the hetero-dimer C₆₀C₅₉N.

Anthracene is demonstrated to enter the tubes but the molecule is

subjected to a considerable geometrical change including some loss of

hydrogens.
