a Summary of correlation between actual EA of materials used as ETL (horizontal axis) and operating voltage of OLEDs with Py-hpp2-doped film at J of 1 mA cm−2 (vertical axis). The electron mobility (μe) of some materials is also shown. b Summary of correlation between operational lifetime (LT50) (horizontal axis) and operating voltage of OLEDs at luminance of 10,000 cd m−2 (vertical axis). LT50 is the time for the luminance to decay by 50% from 10,000 cd m−2.
