Stable and efficient organic light-emitting diodes were prepared using tetradentate platinum-based blue and red emitters. In one example, a series of stable and efficient red phosphorescent OLEDs was fabricated employing a phenyl-pyridyl-carbazole based tetradentate cyclometalated Pt(II) complex as an emitting dopant and utilizing a commercially available host, transporting, and blocking materials. By implementing this platinum complex in electrochemically stable device architectures, long operational lifetimes were achieved with an estimated LT
