  • Patent number: 7261954
    Abstract: Light emitting devices having blocking layers comprising one or more metal complexes are provided. The blocking layers may serve to block electrons, holes, and/or excitons. Preferably, the devices further comprise a separate emissive layer in which charge and/or excitons are confined. Metal complexes suitable for blocking layers can be selected by comparison of HOMO and LUMO energy levels of materials comprising adjacent layers in devices of the present invention.

  • Publication number: 20060280965
    Abstract: An organic emissive layer is provided. Also provided is a device in which the organic emissive layer is disposed between an anode and a cathode. The organic emissive layer includes a phosphorescent material and triphenylene compound or a compound having a repeat unit having a triphenylene moiety. The triphenylene is optionally substituted. The substituents may be the same or different and each is selected from the group consisting of alkyl, aryl, fused aryl, substituted aryl, alkenyl, alkynyl, and heteroalkyl. Triphenylene compounds are also provided.

  • Publication number: 20060269785
    Abstract: Devices are provided having an anode, a cathode, and an emissive layer disposed between and electrically connected to the anode and the cathode. The emissive layer includes an emissive material having more than one metal center. In one embodiment, first and second metal centers are independently selected from the group consisting of d7, d8, and d9 metals. A bridging ligand is coordinated to the first metal center and to the second metal center. In one embodiment, the first and second metal centers each have coordination numbers of at least 3, and more preferably each have coordination numbers of 4. In one embodiment, photoactive ligands are coordinated to the first and second metal centers. In one embodiment, there are no photoactive ligands. In one embodiment, a charge neutral bi-nuclear emissive material is provided. In one embodiment the first and metal centers have a co-facial configuration, and preferably a square planar co-facial configuration.
