| Abstract: | The construction of a square-wave-shaped one-dimensional polyrotaxane using a preorganized L-shaped [3]pseudorotaxane and metal ion is reported. A phenanthroline derivative having two N -(3-pyridylmethyl)-1,4-butanediammonium "arms" was synthesized as a preorganized L-shaped ligand. This L-shaped ligand easily forms a stable [3]pseudorotaxane incorporating cucurbituril (CB[6]). The reaction of the [3]pseudorotaxane with Ni(II) or Zn(II) ion produces a square-wave-shaped one-dimensional-polyrotaxane. |
