Main Results:

  • Achieved highly efficient sky-blue luminescence with quantum yields up to 82% and short lifetimes.
  • Identified Thermally Activated Delayed Fluorescence (TADF) as the emission mechanism.
  • Demonstrated electroluminescence in OLEDs with peak maxima below 470 nm and external quantum efficiencies up to 15.25%.

Conclusions:

  • Gold(III) complexes exhibit promising TADF properties for blue OLED applications.
  • These complexes represent a new class of emitters for high-efficiency blue OLEDs and white OLEDs (WOLEDs).
  • This work paves the way for advanced gold(III)-based optoelectronic devices.
