Used as a key building block in organic synthesis, particularly in the preparation of conjugated polymers and metal-organic frameworks (MOFs). Its terminal alkyne groups enable click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable in materials science for constructing functional nanostructures. Also employed in the development of fluorescent sensors and optoelectronic materials due to its ability to enhance π-conjugation in organic semiconductors.
