摘要：

A triptycene-based homotritopic host was designed and synthesized. Assembly of the host with a bisbenzylammonium salt containing terminal double bonds resulted in a tris[2]pseudorotaxane, which further performed the threefold metathesis reaction and then hydrogenation to give a [4]pseudocatenane in high yield. The [4]pseudocatenane exhibited a novel topological structure with high symmetry, which was confirmed by the spectral data and X-ray analysis. Copyright © 2005 American Chemical Society.
