Two research groups show that it is possible to produce a high-performance pure blue MR-TADF OLED emitter without the need for an assistant dopant
Researchers from the Universities of St Andrews, Kyoto and Kyushu have coincidentally developed state-of-the-art multi-resonant TADF (MR-TADF) OLED emitters, based on a helical boron-nitrogen-oxygen doped nanographene design.
In these multiple studies, the researchers have shown that it is possible to obtain deep blue, narrowband emission, very fast reverse intersystem crossing rates constants, and high-efficiency vacuum-deposited OLEDs.
