Studies from Chinese Academy of Science Describe New Findings in Optical Research

February 18, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Research findings on Optical Research are discussed in a new report. According to news reporting from Suzhou, People's Republic of China, by VerticalNews journalists, research stated, "A new series of phosphorescent iridium (III) complexes based on 5-methyl-2-phenylbenzo[d]oxazole derivatives as main ligands, i.e. bis(5-methyl-2-phenylbenzo[d]oxazole-N,C-2')iridium(acetylacetonate) [(mpbo)(2)Ir(acac)], bis(2-(4-fluorophenyl)-5-methylbenzo[d]oxazole-N,C-2')iridium(acetylacetonate) [(fmbo)(2) Ir(acac)] and bis(5-methyl-2-p-tolylbenzo[d]oxazole-N,C-2') iridium(acetylacetonate) [(mtbo)(2)Ir(acac)], were synthesized for organic light-emitting diodes (OLEDs), and their photophysical, electroluminescent properties were investigated."

The news correspondents obtained a quote from the research from the Chinese Academy of Science, "All complexes have high thermal stability and emit intense phosphorescence from green to yellow at room temperature with high quantum efficiencies and relatively short lifetimes. The OLED based on (fmbo)(2)Ir(acac) as dopant emitter showed very high luminance of 26,004 cd m(-2) and luminance efficiency of 18.5 cd A(-1)."

According to the news reporters, the research concluded: "The evidences indicated that this series of iridium (III) complexes were potential candidates for applications in organic electroluminescent devices."
