abstract = {Antifreeze glycoproteins (AFGPs) from polar fish are the
most potent ice recrystallization (growth) inhibitors known,
and synthetic mimics are required for low-temperature
applications such as cell cryopreservation. Here we
introduce facially amphipathic glycopolymers that mimic the
three-dimensional structure of AFGPs. Glycopolymers
featuring segregated hydrophilic and hydrophobic faces were
prepared by ring-opening metathesis polymerization, and
their rigid conformation was confirmed by small-angle
neutron scattering. Ice recrystallization inhibition (IRI)
activity was reduced when a hydrophilic oxo-ether was
installed on the glycan-opposing face, but significant
activity was restored by incorporating a hydrophobic
dimethylfulvene residue. This biomimetic strategy
demonstrates that segregated domains of distinct
hydrophilicity/hydrophobicity are a crucial motif to
introduce IRI activity, which increases our understanding of
the complex ice crystal inhibition processes.},
