Used as a key intermediate in the synthesis of advanced organic materials, particularly in the development of conjugated polymers and liquid crystalline compounds. Its rigid, linear structure enhances electron delocalization, making it valuable in organic electronics such as OLEDs and field-effect transistors. Also employed in the preparation of nonlinear optical materials and high-performance dyes due to its strong electron-donating properties and thermal stability. Commonly utilized in cross-coupling reactions to build complex aromatic frameworks for pharmaceuticals and agrochemicals.
