Abstract
The invention discloses a compound containing spiro-dimethyl anthracene fluorene and an application of the compound. The compound has a spiro-dimethyl anthracene fluorene structure, so that the compound has high rigidity and the advantages that crystallization and aggregation between molecule cannot be easily formed, and the compound has good film-forming property and the like after being connected with a long-chain branch structure of a carbazole derivative. A parent nucleus of the compound has double polarity, a branch chain is provided with an electron-donating group, the electron donatingabilities of a branch chain group are different, so that HOMO energy levels of a material are different, and the compound can serve as different functional layer materials to be used. The compound hashigher triplet-state energy levels, energy loss can be effectively blocked, and energy transfer is facilitated. The compound serves as an organic light-emitting functional layer material to be applied to an OLED (organic light-emitting diode) device, current efficiency, power efficiency and external quantum efficiency of the device are greatly improved, and the service life of the device is obviously prolonged.
Description
technical field [0001] The invention relates to the technical field of semiconductors, in particular to a compound containing spirodimethylanthracene fluorene and its application in organic electroluminescent devices. Background technique [0002] Organic electroluminescence (OLED: Organic Light Emission Diodes) device technology can not only be used to manufacture new display products, but also can be used to make new lighting products, and is expected to replace the existing liquid crystal display and fluorescent lighting, and has a very broad application prospect. The OLED light-emitting device is a sandwich structure, including electrode material film layers, and organic functional materials sandwiched between different electrode film layers. Various functional materials are superimposed on each other according to the application to form an OLED light-emitting device. As a current device, when a voltage is applied to the electrodes at both ends of the OLED light-emitting...
