High‐performance green emitters for OLEDs have been studied. New green emitters, C‐GEM1, C‐GEM2 and C‐GEM3, showed high efficiency and long lifetime when making devices using each material as an emitter. The optimized device demonstrated an external quantum efficiency of over 6% and a power efficiency of 26 lm/W at 1,000 cd/m 2 with the lifetime of over 25,000 hours.
