Efficient, narrow-band, and stable electroluminescence from organoboronnitrogen-carbonyl emitter
We report a molecular-design strategy, i.e., hybridization of organoboron-nitrogen and carbonyl. OLEDs exploiting binary emitting layers achieve ultrapure emission, a maximum efficiency of over 40% with mild roll-off, and operational stability of LT95~ 137 h of the initial luminance at 1000 nits.
