We reported poly[2]catenane gels prepared by entirely sequential self-assembly of small molecules via noncovalent and dynamic covalent bonds. First, monomer M1 self-assembled into linear supramolecular polymers through hydrogen bonding and π-π interactions. Upon the addition of M2 and M3, dynamic covalent bonds were generated to transform supramolecular polymers into poly[2]catenane gels.
