Used as a key intermediate in the synthesis of conjugated organic semiconductors and optoelectronic materials. Its rigid anthracene backbone and ethynyl functionality enable efficient π-conjugation, making it valuable in the development of organic light-emitting diodes (OLEDs) and field-effect transistors (OFETs). The trimethylsilyl groups enhance solubility and stability during synthetic processing, allowing for easier purification and handling in air-sensitive reactions. It is also employed in Sonogashira coupling reactions to build extended aromatic systems for photovoltaic applications.
