Used as a ligand in coordination chemistry, particularly in the formation of metal complexes for photophysical and electrochemical applications. Its extended aromatic system enhances light absorption and emission properties, making it suitable for use in organic light-emitting diodes (OLEDs) and as a sensitizer in dye-sensitized solar cells. Also employed in the development of molecular sensors due to its ability to selectively bind metal ions and produce detectable optical responses. Its rigid structure supports the design of supramolecular architectures and molecular devices.
