Abstract
PtON1-tBu and PtON6-tBu-doped blue organic light-emitting diodes (OLEDs) demonstrated estimated operational lifetimes LT70 of 174 and 380 h at an initial luminance of 1000 cd/cm2 with CIE coordinates of (0.188, 0.256) and (0.197, 0.309), respectively. Modifying the molecular structure of the lumiphore resulted in a PtON12-tBu-based green OLED, which realized an estimated operational lifetime LT70 of 1410 h at an initial luminance of 1000 cd/cm2 with CIE coordinates of (0.281, 0.559). These studies demonstrate that the tetradentate Pt(II) complexes bearing phenyl-pyrazole or benzopyrazole can act as stable phosphorescent emitters for the development of efficient and stable blue and green OLEDs.
