Abstract
Phosphorescent Pt(II) complexes based on phenylbenzoazole ligands were synthesized and their photophysical properties were investigated for OLEDs. Multilayered OLEDs devices using these complexes as emitters showed the efficient emissions, which are very sensitive to the structural and photophysical properties of Pt(II) complexes. In particularly, a device C using Pt(II) complex 2 based on phenylbenzoazole ligand as the dopant exhibited efficient emission with a luminous efficiency, a power efficiency, an external quantum efficiency, and CIE coordinates of 8.03 cd/A, 2.79 lm/W, 4.84% at 20 mA/cm², and (0.63, 0.35) at 10.0 V, respectively.Entities:
