Abstract
The application discloses an organic compound, an electronic element with the organic compound, and an electronic device including the electronic element. The organic compound of the present application has a fused heteroaromatic group containing fluorenyl or silylfluorenyl as its core structure, which presents a large planar structure in a three-dimensional (3D) space; and an electron-rich arylamine or heteroarylamine substituent is introduced at position 9 of the fluorenyl or silylfluorenyl to make the compound have excellent hole transport performance.
