Used as a key intermediate in organic synthesis, particularly in the preparation of electroactive and photoactive materials. Employed in the development of ionic liquids for electrochemical applications due to its stable radical cation formation. Serves as a building block in supramolecular chemistry for constructing redox-switchable systems and molecular machines. Also applied in surface functionalization for creating modified electrodes in sensors and catalytic devices. Shows potential in photoredox catalysis and as a component in charge-transfer complexes for optoelectronic materials.
