Used as a fluorescent probe in biochemical and analytical applications due to its strong emission properties upon excitation. It serves as a ligand in coordination chemistry, forming complexes with metal ions for use in luminescent materials and sensors. Employed in the development of organic light-emitting diodes (OLEDs) as part of emissive or electron-transport layers. Also acts as a building block in the synthesis of conjugated polymers for optoelectronic devices. Its planar, conjugated structure makes it suitable for studying π-π interactions in supramolecular chemistry.
