Creation of nano magnetic devices using chiral carbon nanotubes and organic molecules

碳纳米管(CNT)是由碳原子组成的圆柱形化合物，具有左手和右手结构。由于碳纳米管具有导电性，我们有一个想法，即它们可能作为微小的电磁铁工作。由于较小的磁场很难直接检测到，我们考虑将磁性分子附着在碳纳米管的表面并观察其作用效果。作为目的的基础，我们利用扫描隧道显微镜(STM)研究了单分子磁性分子(Tb-Ph)双层络合物在碳材料(HOPG)表面的自组装结构。我们制备了质子化、阴离子和自由基形式的Tb-卟啉双层络合物，并在HOPG上测定了它们的超分子结构。

Carbon nanotubes (CNTs) are cylindrical compounds made from carbon atoms, which have left- and right-handed structures. Since the CNTs are electrically conductive, we have an idea that they can possibly work as tiny electrical magnets. Because detection of the small magnetic field will be difficult directly, we considered to use magnetic molecules to attach on the surface of CNTs and to observe the effects of them.As the basis for the aim, we studied self-assembled structure of single molecular magnetic molecules (terbium porphyrin double decker complexes) on the surface of carbon materials (HOPG) by using scanning tunneling microscope (STM). We prepared protonated, anion, and radical form of the terbium porphyrin double decker complexes and determined their supra molecular structures on HOPG.
