Approaching National Television System Committee Blue Gamut Through Asymmetric Modification of MR-TADF Material (Advanced Optical Materials 23/2025)
Deep-Blue MR-TADF Emitter
An ultrapure deep-blue multi-resonance-induced thermally activated delayed fluorescence (MR-TADF) material is reported. The emission color is precisely tuned by controlling the position of oxygen atoms through an asymmetric molecular design strategy. As a result, the developed organic light-emitting diode achieves pure-blue electroluminescence (458 nm) and suppressed efficiency roll-off (EQEmax = 21.7% / EQE1000 = 20.8%). More details can be found in research article https://doi.org/10.1002/adom.202402939 by Takuji Hatakeyama and co-workers.
