高分辨率透射电子显微镜揭示了几乎原子级精确的图像步进构象变化和单烃分子限制在碳纳米管的平移运动。将一个或两个C12或C22烷基链拴在碳硼烷端基上，然后嵌入纳米管中。碳氢化合物链相互作用以及与石墨表面相互作用的图像提供了无法通过其他分析方法获得的三维结构和动态分子相互作用的信息。
High-resolution transmission electron microscopy revealed nearly atomically precise images of stepping conformational change and translational motion of single hydrocarbon molecules confined in carbon nanotubes. One or two C12 or C22 alkyl chains were tethered to a carborane end group and then embedded in the nanotubes. Images of the hydrocarbon chains interacting with each other and with a graphitic surface provide information on three-dimensional structures and dynamic molecular interactions that cannot be obtained by other analytical methods.
