Novel aromatic compounds with specific structural features
The granted patent US12048246B2 outlines a series of claims related to a novel compound represented by Formula I, which can be modified through various substituents. The claims detail the flexibility of substituents (R, R', RA, RB, and RC) that can include hydrogen, deuterium, fluorine, and various organic groups such as alkyl, aryl, and heteroaryl. Specific configurations of the compound are also described, including variations where certain atoms (X1-X3) are nitrogen or carbon, and conditions under which certain groups can form carbazole structures. The patent further specifies that the compound can be part of a broader class of compounds, including those identified by specific numbering formulas.
Additionally, the patent claims the application of the compound in organic light-emitting devices (OLEDs), detailing the structure of these devices, which consist of an anode, cathode, and an organic layer containing the compound. The organic layer may serve as an emissive layer, with the compound functioning as either an emissive or non-emissive dopant. The claims also encompass the use of the compound in consumer products that incorporate OLED technology, as well as formulations that include the compound itself. This patent thus covers both the chemical composition of the compound and its practical applications in advanced electronic devices.
