Disclosed are a spirobifluorene organic light-emitting compound and an organic light-emitting device. The spirobifluorene organic light-emitting compound has a structural formula as shown in formula I. Such a compound can be used as an organic light-emitting material, wherein compared with comparative techniques, the reduction in the planarity of a molecule of the material can effectively improve the effect and scope of use of the material, and the increase in torque and degree of freedom of the molecule of the material effectively improves the hole transport capability of such materials, and adjusts the HOMO energy level of a hole transport material, thereby greatly reducing the driving voltage of an organic light-emitting device, effectively reducing energy consumption, and substantially increasing the lifespan of the organic light-emitting device. |
