Abstract

The construction of a new chiral pentadecanuclear metallamacrocycle using a pentadentate bridging ligand is described. The cyclic system is found to exhibit a sextuple twisted Mobius topology.

Abstract

Suitable designed C3-symmetric facial ligands and C4-symmetric metal ions are used as a general strategy for the preparation of face-driven corner-linked truncated octahedral nanocages. The cavity size and the port size of the cage can be controlled depending on the size of the facial ligands, which offers possibilities of developing suitable nanosized host systems that can accommodate suitable small molecular guests or chiral catalysts.

Abstract

The article examines the utilization of the C3-symmetric facial ligands and C4-symmetric metal ions for the preparation of truncated octahedral nanocages. The curvature needed for truncation at the octahedral vertices was accomplished using ligands with a tilted pyridyl group and a nitrogen donor atom. The nanocages have 12 ports at the edges of the truncated octahedron.
