Here the researchers have developed a new strategy to create red Multiple Resonance (MR) emitters for OLEDs achieves high efficiency and color purity by adjusting the π-conjugation and electron-donating properties within a boron-based structure. The result is a range of emissions with narrow bandwidths and a particularly pure-red device meeting the BT.2020 standard with high quantum efficiency and brightness. This approach suggests a promising direction for developing OLED materials with superior color performance.
How Setfos was used
The experimental EQEs closely aligned with the theoretical efficiencies predicted by optical simulations using Setfos software (33.6% for CzIDBNO and 27.9% for IDIDBNO), which further demonstrated the intricate interplay of these parameters on outcoupling efficiency and overall device performance.
