Abstract
Embodiments are related to the field of organic electroluminescent materials, and in particular to a compound and a use thereof in an organic optoelectronic device. The chemical structure of the compound is as shown in formula (I). The compound is applied to an organic device, which enables the device to have high hole mobility, and to effectively prevent electrons and excitons from entering a hole transport layer, thereby improving the efficiency of the device. In addition, the molecule has high stability, which further improves the light-emitting efficiency and the service life of the device.
