Used as a high-performance crosslinking agent in advanced polymer systems, particularly in the development of thermosetting resins with enhanced thermal stability and mechanical strength. Its rigid adamantane core and multiple ethynyl groups enable efficient formation of three-dimensional networks through thermal or catalytic curing, making it valuable in aerospace composites, microelectronics encapsulation, and high-temperature coatings. The compound also serves as a building block in porous organic frameworks for gas storage and catalysis due to its well-defined geometry and reactive sites.
