Used in organic semiconductor materials due to its electron-transport properties, particularly in OLEDs (organic light-emitting diodes) for display and lighting technologies. Its rigid aromatic structure enhances thermal stability and luminescence efficiency. Commonly employed as a fluorescent probe in bioimaging and sensor applications owing to its strong emission and selective binding to biomolecules. Also serves as a key intermediate in synthesizing pharmaceuticals and agrochemicals where halogen functionality allows further cross-coupling reactions.
