Used as a high-performance crosslinking agent in advanced polymer systems, particularly in the development of heat-resistant and optically clear materials. Its unique structure with multiple ethynyl groups enables efficient thermal curing, making it valuable in aerospace composites and microelectronics encapsulation. Also employed in organic light-emitting diodes (OLEDs) as a building block for rigid, conjugated frameworks that enhance electron transport and device efficiency. Shows promise in molecular electronics due to its star-shaped rigidity and ability to form stable thin films with tunable photophysical properties.
