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.
