Abstract:
Linear side-chain polypseudorotaxane with supramolecular polymer backbone was assembled by neutral halogen bonds (XB) and pillar[5]arene-based host-guest interactions in solution and in the solid state. The formation of the halogen-bonded supramolecular polymer backbone and side-chain polypseudorotaxane in solution was characterized by 1 H NMR spectroscopy, diffusion ordered NMR spectroscopy and scanning electron microscopy experiments. Furthermore, the solid-state structures of these two highly organized supramolecular architectures were provided by single-crystal X-ray analysis.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
