  • NIR TADF OLEDs with a maximum external quantum efficiency of nearly 10% and a maximum radiance value of 3 × 106 mW sr−1 m−2 using a solution-processable D–A–D boron difluoride curcuminoid derivative(EML).
  • By controlling the polarity of the active medium, the maximum emission wavelength of the electroluminescence spectrum can be tuned from 700 to 780 nm.
  • This study represents an important advance in near infrared organic light-emitting diodes and the design of alternative molecular architectures for photonic applications based on thermally activated delayed fluorescence.
