Used as a key intermediate in the synthesis of organic semiconductors and dyes, particularly in the development of phenazine-based functional materials for optoelectronic devices. Employed in photovoltaic cells and organic light-emitting diodes (OLEDs) due to its electron-accepting properties and ability to form stable charge-transfer complexes. Also applied in electrochemical sensors and as a building block in conjugated polymers for flexible electronics. Shows potential in photoredox catalysis and as a component in dye-sensitized solar cells (DSSCs) owing to its strong light absorption and redox activity.
