Abstract

The invention provides anthracene derivatives of a fluorescent green main body material, a hole injection material or a hole transport material, and application of the anthracene derivatives, as well as an organic light-emitting device comprising the organic light-emitting compound. The anthracene derivative has a molecular structure general formula shown in the specification, wherein the structural formula of R is any one of a, b, c, d, e and f. The organic light-emitting device manufactured by the organic light-emitting compound has low connected voltage, long service life, high efficiency and high color purity.

Description

Background technique [0001] Organic electroluminescence (EL) generally consists of two opposing electrodes and at least one layer of organic light-emitting compound interposed between the two electrodes. Charges are injected into the organic layer formed between the anode and cathode to form electron and hole pairs, which cause light emission from organic compounds having fluorescent or phosphorescent properties. [0002] The research on organic EL materials began in 1950 when Bernose applied high current and voltage to polymer films containing organic pigments to observe the luminescence. In 1965, Pope et al. first discovered the electroluminescent properties of anthracene single crystals. [0003] In order to make organic light-emitting devices with high efficiency, researchers have gradually changed the structure of the organic layer in the device from a single layer to a multilayer structure. The EL device is designed as a multilayer structure because the moving speeds of...
