Description

technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to an organic light-emitting compound and an organic light-emitting device thereof. Background technique [0002] Organic optoelectronic materials are organic materials with photon and electron generation, conversion and transport properties. At present, organic photoelectric materials have been applied to organic light-emitting devices (Organic Light-Emitting Diode, OLED). OLED refers to a device in which organic photoelectric materials emit light under the action of current or electric field, which can directly convert electrical energy into light energy. In recent years, OLED as a new generation of flat panel display and solid-state lighting technology is receiving more and more attention. Compared with liquid crystal display technology, OLED is more and more used in the field of display and lighting due to its low power consumption, active light emissio...
