Used as a key intermediate in organic electronics, particularly in the synthesis of conjugated polymers and small molecules for organic field-effect transistors (OFETs) and organic light-emitting diodes (OLEDs). Its extended π-conjugated structure enhances charge carrier mobility and luminescence properties. The trimethylsilylethynyl groups facilitate solubility and enable further functionalization via Sonogashira coupling, making it valuable in constructing complex aromatic systems for optoelectronic materials. Also employed in research on fluorescent sensors and molecular wires due to its stable, rigid backbone and efficient electron transport.
