Used primarily as a key intermediate in the synthesis of organic electronic materials, especially in the production of conjugated polymers for organic solar cells and OLEDs. Its aldehyde functional groups allow for easy extension of the π-conjugated system through condensation reactions, enabling fine-tuning of optoelectronic properties. It is also employed in the development of conductive polymers and sensors due to its stable electroactive framework. Its rigid, planar structure enhances charge transport, making it valuable in designing high-performance organic semiconductors.
