Highly efficient orange phosphorescent organic light-emitting diodes with (4-(3,5-dimethylphenyl)-2-(m-tolyl)pyridine)-based iridium complex
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 l’Eclairage coordinates of (0.49, 0.51).
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 128071-98-7, you can contact me at any time and look forward to more communication. Name: 4-Bromo-2-fluoropyridine.
