Used in organic semiconductor materials due to its stable aromatic structure and electron-accepting properties. Commonly applied in the development of OLEDs (organic light-emitting diodes) as an emissive or charge-transport layer component. Also investigated as a building block in pharmaceutical research for designing kinase inhibitors and other bioactive compounds. Its rigid fused-ring system enhances thermal stability and influences binding selectivity in drug design. Additionally, it serves as a fluorescent probe in biochemical imaging owing to its strong emission characteristics.
