57‐4: Demonstration of Efficient Green OLEDs with High Color Purity

We demonstrated efficient green OLEDs with high color purity utilizing a platin num complex. A current efficiency of 84 cd/A A was obtained from a bottom‐emitting OLED with CIE x‐y coordinates of (0.27, 0.67). Furthermore, the CIE x‐y coordinates reached (0.18, 0.74) upon employing a top‐emitting structure.
