Chirality-Triggered Wettability Switching on a Smart Polymer Surface

Chiral recognition of monosaccharide enantiomers is translated into large-extent wettability switching and other macroscopic surface properties, for example, volume, on a smart copolymer film containing dipeptide units by a cooperative hydrogen-bonding interaction. This work points to a promising direction for developing novel chirality-responsive materials, which find broad applications in controllable chiral separation, chiral medicine, smart biodevices, etc.
