Morphological control and molecular recognition by bis-urea hydrogen bonding in micelles of amphiphilic tri-block copolvmers

摘要

Hydrogen bonding between urea groups of amphiphilic tri-block copolymers considerably affects their self-assembly in water,which results in a strong modification of morphology and viscosity of aqueous solutions;the hydrogen bonding motif in these amphiphilic copolymers allows molecular recognition of small molecules with complementary hydrogen bonding units.
