A benzo[g]phthalazine-containing aromatic heterocyclic compound as represented by formula (I), a preparation method for the compound, and an organic electroluminescent component comprising the compound. The compound as represented by formula (I) is such that groups Q 1 , Q 2 , Ar 1 , Ar 2 , Ar 3 , and Ar 4 are introduced into a benzo[g]phthalazine, increases electron density and skills, and improves the performance of the aromatic heterocyclic compound. The preparation method is simple and easy to be industrialized. The organic electroluminescent component comprising the compound has increased luminous efficacy and service life, increased brightness, and great heat resistance. |
