Stimuli-Responsive Biodegradable Cholesteric Films with Color-Tunable Circularly Polarized Ultralong Room-Temperature Phosphorescence
Circularly polarized luminescence (CPL) has been extensively explored in asymmetric catalysis, chiroptical sensing, and next-generation optoelectronics. Herein, we develop a cellulose-based cholesteric photonic platform incorporating chiral phosphors into hydroxypropyl cellulose (HPC) and cellulose nanocrystal (CNC)...
