The shape transformation of nanoparticles driven by light-induced configurational change of hydrazone-based photoswitches |
| 초록 |
The hydrazone framework exhibits a bistable system that can confine the actuation of dynamic molecules. We report on a reversible shape transformation of nanoparticles driven by light-induced configurational change of hydrazone photoswitches. The designed block copolymers composed of hydrophilic polyethylene glycol blocks and discrete poly(phenyllactic acid) blocks with photoswitches incorporated into specific positions. This system allowed to investigate the effect of photoswitching within the self-assembled BCP structures. Isomerization of the hydrazone-based photoswitch was amplified when embedded in the bilayer membranes of nanoparticles to reversibly tune the self-assembled morphologies, indicating that the position of the switch along the hydrophobic dPPLA chains determines the shape transformation of nanostructures. |
