Used as a key building block in organic electronics and optoelectronic materials due to its rigid, conjugated structure. Its ethynyl groups enable coupling reactions to extend π-systems, making it valuable in synthesizing conductive polymers, organic semiconductors, and metal-organic frameworks. Commonly applied in the development of organic field-effect transistors (OFETs), organic light-emitting diodes (OLEDs), and sensors. Also employed in research for carbon-rich materials and graphene-like structures through surface-assisted synthesis.
