Abstract
En 中文
• Spiropyran photoacid renders surface charges of colloids reversibly light responsive • Control of surface charge allows finely tuned self-assembly of colloidal crystals • Dynamic, light-induced phase transitions between gas, gel, and crystal are studied • Spatial and temporal patterned light controls crystal positions, shapes, and sizes
