Pillar[5]arene-based supramolecular polypseudorotaxane polymer networks constructed by orthogonal self-assembly

A novel pillar[5]arene-based supramolecular polypseudorotaxane network constructed by orthogonal self-assembly has been successfully fabricated. The obtained supramolecular polypseudorotaxane polymer was formed by a combination of two different non-covalent interactions, quadruple hydrogen bonding and pillararene-based host-guest interactions. Furthermore, a translucent film could be generated from the combination of this supramolecular polymer with PEG-2000 as the polymer matrix. The present study will provide a convenient and efficient way for the creation of pillararene-based advanced supramolecular materials.
