Used as an organic semiconductor building block in the fabrication of conductive polymers and optoelectronic devices. Its rigid, planar structure enhances π-conjugation, making it suitable for applications in organic field-effect transistors (OFETs) and dye-sensitized solar cells. Also employed in the synthesis of fluorescent probes and sensors due to its electron-withdrawing properties and ability to form stable imine linkages. Shows potential in developing metal-organic frameworks (MOFs) for gas sensing and catalysis.
