Used as a key intermediate in organic synthesis, particularly in the development of conjugated polymers and optoelectronic materials. Its extended π-conjugated structure makes it suitable for applications in organic semiconductors, solar cells, and light-emitting diodes (OLEDs). Also employed in the preparation of functional dyes and sensors due to its redox-active properties and ability to undergo charge transfer interactions. Its rigid backbone supports thermal stability and enhances electron delocalization in electronic devices.
