Used as a key building block in the synthesis of metal-organic frameworks (MOFs) and coordination polymers due to its multidentate ligand structure. Its pyridine groups readily coordinate with transition metals, making it valuable in catalysis and porous material design. Also explored in supramolecular chemistry for constructing molecular sensors and switches, especially in systems responsive to pH or metal ion stimuli. Shows potential in electrochemical applications, including ligand frameworks for fuel cell catalysts and conductive materials.
