Used as a key intermediate in the synthesis of liquid crystal materials for display technologies. Its conjugated structure and functional groups allow for effective charge transport and molecular alignment, making it suitable for organic semiconductors and optoelectronic devices. Also employed in the development of fluorescent dyes and sensors due to its strong light-emitting properties when incorporated into larger aromatic systems. Its carboxylic acid group enables covalent attachment to surfaces or polymers, useful in surface modification and sensor fabrication.
