Used in organic semiconductor materials due to its electron-deficient aromatic structure, enhancing electron transport in thin-film transistors. Employed as a building block in synthesizing fluorescent dyes and luminescent compounds for OLEDs and sensors. Acts as a ligand precursor in catalysis, particularly in palladium-catalyzed cross-coupling reactions. Investigated for photovoltaic applications in organic solar cells owing to its planar, conjugated framework that supports charge delocalization. Also explored in medicinal chemistry for its potential antimicrobial and antitumor activity, leveraging the quinoxaline core’s bioactivity.
