This research project aims to develop novel metal-containing nanotubes by metal-assisted self-assembly of macrocyclic ligands with a defined diameter. As a building block, cylindrical and disc-shaped ligands were designed and the construction of tubular structures by metal-assisted self-assembly was investigated.A calix[6]arene-based ligand bearing pyridyl groups at the upper rim was synthesized. The complexation of the ligand with palladium(II) afforded coordination polymer that presumably has a tubular structure. When a macrocyclic hexaoxime ligand was reacted with zinc(II) acetate, a dimeric hexanuclear complex with a unique structure was formed. The structure of the complex was determined by X-ray crystallography. Metal-assisted self-aggregation of a dinickel(II) metallohost obtained from a disc-shaped bis(saloph) ligand was also studied.

该研究项目旨在通过具有确定直径的大环配体的金属辅助自组装来开发新型含金属纳米管。作为构件，设计了圆柱形和盘形配体，并研究了金属辅助自组装管状结构的构建。合成了上缘带有吡啶基的杯[6]芳烃基配体。配体与钯(II)的络合提供了可能具有管状结构的配位聚合物。当大环六肟配体与乙酸锌(II)反应时，形成具有独特结构的二聚六核配合物。通过X射线晶体学测定了复合物的结构。还研究了从盘状双（saloph）配体获得的二镍（II）金属主体的金属辅助自聚集。
