홈페이지논문 초록 (Abstract)
A new (4-(3,5-dimethylphenyl)-2-(m-tolyl)pyridine)-based iridium complex was synthesized for highly efficient orange phosphorescent organic light-emitting diodes (PhOLEDs). The effect of introduction of a methyl substituent into the 4-position of the phenyl ring in a phenylpyridine chelating ligand was studied. The PhOLEDs based on this newly-synthesized iridium complex exhibited maximum external quantum and current efficiencies of 20.33% and 61.16 cd/A, respectively. These respective values maintained over 15% and 48 cd/A even at a very high luminance of 15000 cd/m(2) with Commission Internationale de lEclairage coordinates of (0.49, 0.51).
