The invention discloses a boron-containing high-efficiency organic electroluminescence compound and an application thereof. The structural formula of the compound is shown in general formula (1), with a boron atom as the core, and three carbon-carbon single bond combinations extending outward. A six-membered ring is formed, in which the carbon-carbon single bond can also be replaced by carbon-oxygen and carbon-nitrogen single bonds; a benzene ring is sandwiched between every two six-membered rings, and each benzene ring is externally connected to hydrogen, aryl, and heteroaryl. , alkyl, alkoxy, or arylamine groups. The material has good fluorescence quantum efficiency and electroluminescence efficiency, is easy to form an amorphous thin film, and has good thermal stability, so this kind of material can be used as a light-emitting layer material in an organic electroluminescence device. |
