Used as a ligand in coordination chemistry, particularly in catalysis and the synthesis of metal-organic frameworks. Its vinyl group allows for polymerization, enabling the creation of functional polymers with embedded metal-binding sites. Commonly applied in the development of luminescent materials and sensors due to its ability to form stable complexes with transition metals like ruthenium and iridium. Also utilized in electrochemical devices and as a building block in supramolecular chemistry for constructing complex architectures with tailored electronic properties.
