The invention discloses a compound based on xanthone and its application. The compound uses xanthone as the mother nucleus and is connected with an aromatic heterocyclic group, which destroys the symmetry of the molecule, thereby destroying the crystallinity of the molecule, avoiding the Intermolecular aggregation has good film-forming properties. The compound of the present invention is applied to an organic light-emitting diode as a light-emitting layer material, and the OLED device using the compound of the present invention has good photoelectric performance and can meet the requirements of panel manufacturers. |
