Used as a crosslinking agent in polymer chemistry, particularly in the synthesis of functionalized conjugated systems for optoelectronic materials. Its rigid alkyne core and reactive pyridyl ester end groups enable controlled coupling reactions, making it valuable in constructing metal-organic frameworks (MOFs) and supramolecular architectures. Also employed in click chemistry applications where selective, high-yield reactions are required under mild conditions. Its structural geometry supports the development of liquid crystalline phases and conductive polymers when coordinated with transition metals.
