Used as a specialty diamine monomer in high-performance polymer synthesis, particularly in the development of selenium-containing polyamides and polyimides. Its unique selenium-based bridge imparts enhanced thermal stability and improved oxidative resistance to the resulting polymers. The compound is also explored in conductive and optoelectronic materials due to selenium’s polarizability and electronic properties. Additionally, it serves as a building block in coordination chemistry for designing metal-organic frameworks with redox-active sites. Its reactivity allows for functionalization in advanced material science applications, including sensors and semiconducting thin films.
