High Efficiency 3‐Tandem Top Emitting Pure‐Blue OLEDs Beyond the BT.2020 Blue Standard

Advanced Optical Materials, Volume 14, Issue 29, 7 August 2026.
We report a high‐efficiency ultrapure‐blue 3‐tandem TEOLED through synergistic optimization of a narrowband MR‐TADF emitter, Purcell‐based cavity design, and pure Ag cathode/CPL structure. The optimized device achieves 463 nm emission, an ultranarrow FWHM of 10 nm, CIE y of 0.040, and a blue index of 1,596 cd/A/y, surpassing the BT.2020 blue standard ...

Benzo[b]Thiophene‐Derived Low‐T1 Multi‐Resonance Emitter with Suppressed Thermally Activated Delayed Fluorescence for Extending Organic Light‐Emitting Diode Lifetime by Managing Triplet‐Related Bimolecular Interactions

Advanced Optical Materials, Volume 14, Issue 31, August 21, 2026.
Introducing a 5‐phenylbenzo[b]thiophene unit into the DABNA core lowers the T1 level, enlarging the ΔEST to suppress TADF. This molecular design preserves narrow deep‐blue emission while drastically reducing triplet‐related degradation. Consequently, the resulting emitter, BN‐TPh‐TPA, delivers a threefold operational lifetime over the TADF‐active t ...
