一系列的单和双官能化富勒烯已被合成并插入到单壁碳纳米管。通过高分辨率透射电子显微镜和X射线衍射研究了富勒烯官能团的大小和形状对纳米管内形成的一维阵列的影响。向富勒烯笼中添加非平面的空间体积大的链导致高度有序的1D结构，其中富勒烯沿内部纳米管腔沿着均匀间隔。理论计算表明，官能团与相邻的富勒烯笼相互作用，使富勒烯均匀地分布在纳米管的范围内。在富勒烯笼的相对侧添加两个官能团导致以较低的纳米管填充率为代价的纳米管内富勒烯笼的分离的进一步增加。
A range of mono- and bis-functionalised fullerenes have been synthesised and inserted into single-walled carbon nanotubes. The effect of the size and shape of the functional groups of the fullerenes on the resultant 1D arrays formed within the nanotubes was investigated by high resolution transmission electron microscopy and X-ray diffraction. The addition of non-planar, sterically bulky chains to the fullerene cage results in highly ordered 1D structures in which the fullerenes are evenly spaced along the internal nanotube cavity. Theoretical calculations reveal that the functional groups interact with neighbouring fullerene cages to space the fullerenes evenly within the confines of the nanotube. The addition of two functional groups to opposite sides of the fullerene cages results in a further increase in the separation of the fullerene cages within the nanotubes at the cost of lower nanotube filling rates.
