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

Showed that optical states can be reset multiple times using water vapor

Abstract

A chiral molecule-doped polymer system exhibiting reversible photoswitching of red luminescence and chiroptical activity via radical transitions was presented here. The optical state is reversibly reset by water vapor, enabling...
