摘要： Compounds comprising a ligand LA selected from the group consisting of Formula I and Formula II may be useful as blue phosphorescent materials in OLED devices. The materials were determined computationally to have appropriate triplet energies for use as blue emitters and to possess sufficient chemical stability for use in devices.

摘要： 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.

摘要： A compound comprising a first ligand LA of Formula I,
is provided. In Formula I, moiety A and moiety B either a monocyclic ring or a polycyclic fused ring system; each of X1 to X4, Z1, and Z2 is C or N; K1 is a direct bond, O, S, N(Rα), P(Rα), B(Rα), C(Rα)(Rβ), or Si(Rα)(Rβ); L1 is a direct bond or a linking group; each Rα, Rβ, RA and RB is hydrogen or a General Substituent; and LA is coordinated to a metal M. In addition, RA or RB alone or in combination with a substituent of L1 form a 7-membered ring. Formulations, OLEDs, and consumer products containing the compound are also provided.-

摘要： 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.

摘要： 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.
