| Research Abstract |
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.
