Abstract
We examined the impact of chemical degradations at the HTL/EML interface on blue OLED performance. Our study showed that photo‐induced C‐N dissociation of HTL materials has little effect on the blue OLED lifetime while photochemical reactions with water/oxygen on the HTL surface can severely degrade the device efficiency and lifetime.
