Compound with specific ligand formula for organic light emitting devices
A recently granted patent (Publication Number: US11778897B2) discloses a compound with a specific ligand formula that can be used in various applications. The compound consists of a first ligand (LA) with a formula selected from a specific group. The compound can be used in organic light-emitting devices (OLEDs) as an emissive or non-emissive dopant in the organic layer between the anode and cathode. The organic layer may also include a host material with specific chemical groups. The compound can also be used in consumer products that incorporate OLED technology.
The compound described in the patent has various configurations and options. The metal (M) in the compound can be selected from a group of elements including Ir, Rh, Re, Ru, Os, Pt, Pd, Au, and Cu. The ligand LA can have different structures and can be selected from specific groups of ligands. The compound can have different combinations of ligands (LB and LC) and their quantities (x, y, and z) depending on the oxidation state of the metal. The ligands LB and LC can also be selected from specific groups.
The patent provides specific examples of compounds and their formulas, such as Ir(LA)i3, Ir(LA)i(LB)2, and Ir(LA)i2(LC)j, where i and j are integers within certain ranges. The ligand LB in these compounds has specific structures.
Overall, this patent discloses a compound with a specific ligand formula that can be used in OLEDs and consumer products. The compound offers flexibility in terms of metal selection, ligand structures, and combinations, allowing for customization based on the desired application. The patent provides specific examples and configurations to guide the implementation of the compound in various devices and formulations.
