The invention relates to a boron-containing organic compound and application thereof to an organic light-emitting device, belonging to the technical field of semiconductors. The structure of the boron-containing organic compound is shown as a general formula (1). The invention also discloses the application of the boron-containing organic compound in an organic electroluminescent device. Accordingto the boron-containing organic compound, the whole molecule of the compound is of a large rigid structure, the planarity of a material is reduced through introduction of substituent groups, the steric hindrance of the material is increased, the material is not prone to rotation, a three-dimensional space structure is more stable, and therefore, the compound has high glass transition temperatureand molecular thermal stability; in addition, the HOMO and LUMO distribution positions of the compound are separated from each other, so the compound has appropriate HOMO and LUMO energy levels. Therefore, after the compound is applied to the OLED device, the luminous efficiency of the device can be effectively improved, and the service life of the device can be effectively prolonged.
