Enhancing the stability and emission efficiency of circularly polarized luminescent materials for deep blue applications

Abstract

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