Abstract

We report a novel solution-processable high molecule iridium complex, bis[5-methyl-7-trifluoro methyl-5H-enzo(c)(1,5)naphthyridin-6-one]iridium(picolinate) (CF3BNO), that exhibits a relatively short excited-state lifetime (0.30 μs) and extremely high quantum yield (95%). Current efficiency of 89.1 cd A−1 at 100 cd m−2 was obtained by using the CF3BNO complex to fabricate a blue-green light-emitting device.
