Triazatruxene Decorated Multi-Resonance Emitter with Hybrid Short-and Long-Range Charge-Transfer Excited States Enables Efficient Narrowband Deep-Blue Electroluminescence

YGYing GaoXGXiaoyu GuoBXBingjie Xie

Key Points

  • The aim is to develop a triazatruxene-based TADF emitter that combines different excited states to achieve narrowband deep-blue emission.
  • Design of a TADF emitter by grafting triazatruxene onto a multi-resonance framework.
  • Characterization of the emitter's excited states and emission properties.
  • Evaluation of the electroluminescence performance under various conditions.
  • Achieved narrowband deep-blue emission with significantly enhanced efficiency.
  • Demonstrated a hybrid mechanism combining short- and long-range charge-transfer states.

Abstract

A TADF emitter with hybrid short- and long-range charge-transfer excited states is designed by grafting the triazatruxene donor onto the multi-resonance framework. The emitter exhibits narrowband deep-blue emission with enhanced...
