Used as a key intermediate in the synthesis of organic semiconductors and liquid crystal materials. Its rigid aromatic structure and silyl groups enhance thermal stability and solubility in nonpolar solvents, making it suitable for solution-processable electronic devices. Commonly employed in the preparation of high-performance polymers for OLEDs and thin-film transistors. The carboxylic acid and amide functionalities allow for further chemical modification, enabling tailored molecular design in optoelectronic applications.
