  • Patent number: 9224963
    Abstract: 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 LT97 of over 600 hrs at luminance of 1000 cd/m2.

  • Patent number: 9203039
    Abstract: A platinum (II) complex of the general formula (I) or (II), in which Ar1, Ar2, and Ar3 are each independently aryl, heteroaryl, or heterocyclic. Ar1, Ar2, and Ar3 together form a tridentate ligand coordinated to the platinum through atoms X, Y, and Z, respectively, and X, Y, and Z are independently carbon or nitrogen. V is a bridging group or a covalent bond, and W is an anion. In general formula (I) in some cases, Ar1 is an anion and Ar2 and Ar3 are neutral; in other cases, Ar1 and Ar3 are neutral and Ar2 is an anion. In general formula (II), in some cases, Ar3 is an anion and Ar1 and Ar2 are neutral; in other cases, Ar1 and Ar3 are neutral and Ar2 is an anion. The complexes are asymmetric. The complexes emit in the UV to near IR range and are useful as emitters for organic light emitting devices.
