Abstract :
A new hybrid material C10H2@SWNTs, single-wall carbon nanotubes (SWNTs) encapsulating C10H2 polyyne molecules, has been synthesized and confirmed by Raman spectroscopy and X-ray diffraction measurement. The C10H2 polyyne molecules composed of linearly bonded sp-carbon atoms are aligned inside the SWNTs. This hybrid material exhibits a characteristic Raman signal at 2066 cm−1 attributable to the stretching vibration of the C10H2 molecules interacting with SWNTs. Being trapped inside the SWNTs, the otherwise unstable C10H2 molecules are shown to be stable well above 300 °C under dry-air conditions.
