2,3-Diphenylquinoxaline serves as a key precursor in the synthesis of advanced organic materials, including light-emitting diodes (OLEDs) and photovoltaic devices. Researchers utilize its rigid aromatic structure to develop novel ligands for transition metal catalysis or as a fluorophore in sensor design. In medicinal chemistry, it is explored as a scaffold for bioactive molecules targeting kinases and other enzymes. Its electron-accepting properties make it valuable in charge-transfer complexes and conjugated polymers.
