  • Organic electroluminescent materials and devices
    Patent number: 10147892
    Abstract: Compounds that act as capture agents to sequester unsaturated metal complexes are provided. In particular, the compounds may be host materials, dopant materials, or dopant materials containing functional groups, such as an isocyanide or a phosphine group, which are suitable for trapping an unsaturated coordination complex. These compounds may be used in organic light emitting devices, particularly blue devices, to provide improved device lifetime.
    Type: Grant
    Filed: January 28, 2016
    Date of Patent: December 4, 2018
    Assignee: THE UNIVERSITY OF SOUTHERN CALIFORNIA
    Inventors: Mark E. Thompson, Alberto Bossi, Peter Djurovich
  • ORGANIC ELECTROLUMINESCENT MATERIALS AND DEVICES
    Publication number: 20160141524
    Abstract: Compounds that act as capture agents to sequester unsaturated metal complexes are provided. In particular, the compounds may be host materials, dopant materials, or co-dopant materials containing functional groups, such as an isocyanide or a phosphine group, which are suitable for trapping an unsaturated coordination complex. These compounds may be used in organic light emitting devices, particularly blue devices, to provide improved device lifetime.

  • Luminescent Cyclometallated Iridium (III) Complexes Having Acetylide Ligands
    Publication number: 20150076470
    Abstract: The present invention relates to phosphorescent (triplet-emitting) organometallic materials. The phosphorescent materials of the present invention comprise Ir(III)cyclometallated alkynyl complexes for use as triplet light-emitting materials. The Ir(III)cyclometallated alkynyl complexes comprise at least one cyclometallating ligand and at least one alkynyl ligand bonded to the iridium. Also provided is an organic light emitting device comprising an anode, a cathode and an emissive layer between the anode and the cathode, wherein the emissive layer comprises a Ir(III)cyclometallated alkynyl complex as a triplet emitting material.
