Used as a high-performance crosslinking agent in advanced polymer systems, particularly in the development of heat-resistant and optically clear polyimides. Its rigid, three-dimensional adamantane structure enhances thermal stability and reduces chain mobility, making it ideal for aerospace and microelectronics applications where dimensional stability under extreme conditions is critical. The compound’s extended aromatic core with methoxy groups improves solubility in polar aprotic solvents, facilitating processing in thin-film applications such as dielectric layers and flexible displays. Also explored in specialty membranes for gas separation due to its well-defined free volume and molecular sieving characteristics.
