Used as a building block in organic semiconductors and conjugated polymers due to its rigid, linear structure and extended π-conjugation. Enhances charge transport in organic field-effect transistors (OFETs) and serves as a precursor in the synthesis of conductive frameworks for optoelectronic devices. Also employed in the development of metal-organic frameworks (MOFs) with tailored porosity for sensing applications. Its ethynyl groups allow for Sonogashira coupling, enabling modular construction of complex aromatic systems for use in photovoltaics and light-emitting diodes (OLEDs).
