Enhancing the Stability and Emission Efficiency of Circularly Polarized Luminescent Materials for Deep Blue Applications

Abstract

Circularly polarized luminescent (CPL) materials are vital for advanced optoelectronics, especially wide-color-gamut OLED displays. Here, BINAP-based enantiomers were synthesized via one-step methylation, yielding deep blue emission (CIEy<0.08) with high thermal stability and antioxidative properties, addressing challenges in blue-emitting CPL design for efficient, stable, and commercializable applications.
