Markedly high‐efficiency phosphorescent green organic light‐emitting diode can be easily fabricated via solution process by the use of a novel iridium complex, bis[5‐methyl‐7‐trifluoromethyl‐5H‐ benzo (c) (1,5) naphthyridin‐ 6‐ one] iridium (picolinate) (CF 3 BNO). The resultant power (current) efficiency, at 100 cd/m 2 , was 70 lm/W (89 cd/A), while 21 lm/W (35 cd/A) by using typical vapor deposition. Besides proper device architecture design, the high efficiency may be attributed to the high quantum yield of the CF 3 BNO iridium complex.
