Used as an organic ligand in coordination chemistry to form metal-organic frameworks (MOFs), enabling applications in gas storage and catalysis. Its pyridyl groups readily bind to metal ions, creating porous structures ideal for selective adsorption of gases like CO₂ and H₂. Also investigated in optoelectronic devices due to its electron-donating properties and structural rigidity, supporting charge transport in thin-film semiconductors. Shows potential in sensor development for detecting metal ions in environmental and biological systems.
