| Research Abstract |
Nanotube is an attractive nanoscale motif since it can be used for selective recognition and assembly, selective reaction, and transport of small molecules utilizing its cavity. In this work, we have designed a descrete supramolecular nanotube consisted of metal ions and three oligoureas having peripheral bis(hydroxypyrone)-type ligands, which is expected to form planer [3+3] macrocyclic metal complexes with square planar metal ions such as Cu^<2+> and Pd^<2+>. UV-Vistitration and ESI-TOF MS measurement revealed that an urea containing two peripheral bis(hydroxypyrone) ligands formed a discrete trimeric assembly via complexation with Cu^<2+> in MeOH in the presence of DBU.
