The invention discloses a compound based on xanthone and an application thereof. The compound takes xanthone as a parent nucleus, connects aromatic heterocyclic groups, destroys the symmetry of the molecule, thereby destroys the crystallinity of the molecule and avoids the Intermolecular aggregation, with good film-forming properties. The compounds of the present invention are applied to organic light-emitting diodes as light-emitting layer materials, and the OLED devices using the compounds of the present invention have good optoelectronic properties and can meet the requirements of panel manufacturers. |
