Used in organic light-emitting diodes (OLEDs) as a building block for conjugated polymers and small molecules due to its stable aromatic structure and good charge transport properties. Commonly employed in the development of blue-emitting materials for display and lighting technologies. Also serves as a precursor in the synthesis of pharmaceuticals, dyes, and specialty polymers. Its derivatives are utilized in research for photovoltaic materials and sensors because of their fluorescence and electrochemical behavior.
