Used in the synthesis of advanced organic materials, particularly in the development of conductive polymers and organic semiconductors. Its diamine and diethynyl groups make it a valuable building block for creating conjugated systems, which are essential in organic electronics such as OLEDs, solar cells, and field-effect transistors. Additionally, it serves as a precursor for the preparation of metal-organic frameworks (MOFs) and other porous materials, which find applications in gas storage, catalysis, and sensing. Its ability to form stable, extended networks also makes it suitable for designing molecular wires and other nanoscale devices.
