  • ORGANIC ELECTROLUMINESCENT MATERIALS AND DEVICES
    Publication number: 20230276696
    Abstract: The present invention includes novel heterocyclic materials for use as blue phosphorescent materials in OLED devices. The materials are based on carbene and heterocyclic 5-membered ring linked ligands, which may be complexed to a transition metal via a metal-carbon (carbene) bond and a metal-nitrogen covalent bond.

  • ORGANIC ELECTROLUMINESCENT MATERIALS AND DEVICES
    Publication number: 20230006146
    Abstract: Compounds that are organic radicals that can have a dual function. The compounds can be fluorescent emitters that emit in the near-IR. The compounds can also facilitate reverse intersystem crossing (RISC) to convert triplet excitons in an OLED to singlet excited states to maximize utilization of generated excitons in the OLED and approach 100% internal quantum efficiency.

  • Organic electroluminescent materials and devices
    Patent number: 11495757
    Abstract: The present invention includes novel platinum complexes with tridentate ligands forming dimeric structures that are calculated to have blue emission. The ligand backbone and pendant donor rings can be altered to give different emission maxima. The present invention also includes various pendant donor rings and multiple different ligand backbones. Such complexes are suitable for use as an emitter in organic light emitting devices.

  • Organic electroluminescent materials and devices
    Patent number: 11201299
    Abstract: The present invention includes novel heterocyclic materials for use as blue phosphorescent materials in OLED devices. The novel materials include two fused 5-membered aromatic or pseudoaromatic rings, which are bonded with 6 membered aromatic rings to serve as chelation ligands for a transition metal. The novel materials were determined computationally to have appropriate triplet energies for use as blue emitters and to possess sufficient chemical stability for use in devices.
