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.
