Thermo-Responsive Silver Nanocube Assembled Films

Cube-structured silver nanoparticles (AgNCs) were synthesized and modified with oligo(ethylene glycol) (OEG)-attached alkane-thiol ligands. They showed thermo-responsive color changes dispersed in water and also good dispersibility in CHCl3. They formed well-packed assembled structures at the air-water interface. AgNC assembled films also showed a strong plasmonic property and thermo-responsiveness.
