| abstract |
The invention discloses a five-membered ring substituted compound with xanthone as the core and an application thereof. The compound uses xanthone as the core to connect aromatic heterocyclic groups, which destroys the symmetry of the molecule, thereby destroying the molecule The crystallinity avoids intermolecular aggregation and has 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. |
