Abstract: Provided is a new composition of matter for phosphorescent emitters containing a chelating ligand including five or more fused carbocyclic or heterocyclic rings that form two bonds to a metal forming a 7-membered chelate. This fused ring structure provides added rigidity to the molecule for enhanced stability in an OLED device and improve photophysical properties.

Abstract: An OLED structure including a first organic layer disposed between the anode and the cathode is disclosed. The first organic layer includes a primary phosphorescent emitter and a first host, and where one of the following conditions is true: (1) the first organic layer further includes a secondary emitter; or (2) the OLED further includes a second organic layer disposed between the anode and the cathode, wherein the second organic layer includes a secondary emitter. The phosphorescent emitter has a peak emission wavelength λmax that is ≥600 nm and ≤750 nm, the secondary emitter has a peak emission wavelength λmax that is ≥750 nm, and the first host has a lowest excited state triplet energy T1 that is at least 0.1 eV higher than that of the primary phosphorescent emitter.

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.
