Advanced Materials, EarlyView.Heptazine‐assisted MR‐TADF emitters enable narrowband yellow emission with high efficiency at high luminance in solution‐processed OLEDs. In doped films, HAP‐3CzBN achieves a record‐fast kRISC of 1.19 × 106 s−1. The optimized HAP‐3CzBN devices deliver 15.5% EQEmax with negligible roll‐off at 1000 cd m−2, 11.2% at 10,000 cd m−2, and a benchmark 20.3 ...
