Heptazine‐Assisted Multi‐Resonance TADF Emitters With Fast Reverse Intersystem Crossing for Efficient Solution‐Processed OLEDs

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 ...

Role of the Recombination Zone in Organic Light‐Emitting Devices

Advanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Perspective: OLED Displays Singing with the Blues

Advanced Materials, EarlyView.
While blue pixels consume approximately 50% of the energy of OLED display front planes, in the 25 years since their invention, 100% internal efficiency triplet‐controlled phosphorescent OLEDs have not met the stability standards necessary for their adoption.
