Synthesis and Electroluminescent Properties of Ir(III) Complexes Containing Alkenyl Pyridine Ligands

초록

The synthesis and electroluminescent properties of two red Ir(III) complexes based on alkenyl pyridine derivatives, (BzPP)(2)Ir(acac) and (IQP)(2)Ir(acac) are reported. Multilayered, organic light-emitting diodes (OLEDs) were fabricated using (BzPP)(2)Ir(acac) as dopant material. A maximum luminance was 6996 cd/m(2) at 12 V, a maximum luminous and power efficiency were 8.54 cd/A, and 8.16 lm/W, respectively, were achieved. This device showed the deep red emission with the CIE coordinates of (0.66, 0.34) at 10 V.
