Abstract

Abstract A novel yellowish-green triplet emitter, bis (5-(trifluoromethyl)-2-p-tolylpyridine)( acetylacetonate) iridium (III)(1), was conveniently synthesized and used in the fabrication of both monochromatic and white organic light-emitting diodes (WOLEDs). At the optimal doping concentration, monochromatic devices based on 1 exhibit a high efficiency of 63 cd A− 1 (16.3% and 36.6 lm W− 1) at a luminance of 100 cd m− 2. By combining 1 with a ...
