Beyond Hyperfluorescence: Leveraging a Host‐Guest Exciplex to Significantly Suppress the Efficiency Roll‐Off and Improve the Operational Stability in Narrowband Emissive Devices

being the highest and the efficiency roll-off being the lowest among narrowband OLEDs (including hyperfluorescence ones) based on DtBuCzB reported so far. The device also shows markedly improved operational stability compared to counterpart devices using the other two hosts or counterpart hyperfluorescence devices.
