Photochromism via Reversible Transformation of Photoinduced Chiral Free Radicals

Key Points

• To explore the reversible transformations in chiral molecules that lead to photoswitching effects.
• Developed a chiral molecule-doped polymer system
• Investigated photoswitching of red luminescence
• Examined chiroptical properties and their reversibility using water vapor
• Successfully achieved reversible photoswitching of luminescence
• Demonstrated change in chiroptical activity via radical transitions
• Showed that optical states can be reset multiple times using water vapor
