- Abstract
- A new orange phosphorescent iridium complex, Ir(2,4,5-F(3)dpq)(2)(acac), was designed and synthesized, where 2,4,5-F(3)dpq represents 2-(2,4,5-trifluorophenyl)-4-phenylquinoline. Its photoluminescence (PL) maxima occurred at 577 nm. The organic light-emitting diode (OLED) device employing Ir(2,4,5-F(3)dpq)(2)(acac) as a dopant in the emitting layer showed orange electroluminescence (EL) centered at 585 nm. The white-OLED (WOLED) was fabricated by combining this orange phosphorescence from Ir(2,4,5-F(3)dpq)(2)(acac) and the blue fluorescence from 2-(2-hydroxyphenyl)benzoxazolato lithium (LiPBO). Combination of orange and blue emission at 585 nm and at 435 nm resulted in white light emission with CIE coordinates of (0.426, 0.360) and (0.376, 0.319) at 8 V and 14 V, respectively.
