在保持在0 ℃的C-60饱和吡啶和异丙醇的混合物中制备由C-60富勒烯分子组成的结晶微管（内径240-2100 nm）。通过透射电子显微镜的表征显示C-60富勒烯管的外径和内径之间的线性关系。光学观察表明，当它们在溶液中生长时，样品已经具有管状结构。客体晶体在C-60富勒烯管内的沉积通过以下步骤进行：（i）超声粉碎以获得具有开口端的C-60富勒烯管，（ii）通过毛细管吸引将KBr的甲醇溶液吸收到管中，和（iii）蒸发甲醇以在管内沉淀KBr。然后通过将富勒烯管壁溶解在甲苯中获得柱状KBr晶体。
Crystalline microtubes (inner diameter 240-2100 nm) consisting of C-60 fullerene molecules were prepared in the mixture of C-60-saturated pyridine and isopropyl alcohol kept at 0 degrees C. Characterization by transmission electron microscopy showed a linear relationship between the Outer diameter and the inner diameter for the C-60 fullerene tubes. Optical observations Suggested that the specimens already had tubular structure when they were grown in the Solution. Deposition Of guest crystals inside the C-60 fullerene tubes was performed by the following procedure: (i) ultrasonic pulverization to obtain the C-60 fullerene tubes with open ends, (ii) absorption of methyl alcohol Solution of KBr into the tubes by the capillary attraction, and (iii) evaporation of methyl alcohol to precipitate KBr inside the tubes. Columnar KBr crystals were then obtained by dissolving the fullerene tube walls in toluene.
