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, EarlyView.
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 ...
