High-performance narrowband blue electroluminescence with EQE approaching 20% based on hybridized local and charge-transfer multi-resonant molecules

Year: 2025

Type: article

Abstract: -isomer 4CzpICz achieves record HLCT-OLED performance: a narrowband device (FWHM = 29 nm) with 19.5% external quantum efficiency (EQE). In an exciplex-sensitized configuration, EQE reaches 25.0% without emission broadening. This work pioneers MR-HLCT integration and establishes a roadmap for next-generation OLED materials.
