合成了一种新型的杂化材料C10H2@SWNTs，即单壁碳纳米管（SWNTs）包裹C10 H2聚炔分子，并通过拉曼光谱和X射线衍射进行了表征。由线性键合的sp-碳原子组成的C10 H2聚炔分子排列在单壁碳纳米管内部。该杂化材料在2066 cm（-1）处表现出特征性的拉曼信号，这归因于C10 H2分子与SWNT相互作用的伸缩振动。被困在单壁碳纳米管内部，否则不稳定的C10 H2分子被证明在干燥空气条件下在300摄氏度以上是稳定的。(c)2006 Elsevier B. V.保留所有权利。
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 degrees C under dry-air conditions. (c) 2006 Elsevier B.V. All rights reserved.
