Used in organic electronics as a nonlinear optical material, particularly in second-harmonic generation (SHG) applications due to its strong polarized structure. Commonly employed in thin-film coatings for electro-optic devices and photonic crystals. Also utilized in research settings for fluorescence imaging and as a dye in membrane studies owing to its lipophilic cationic nature, allowing interaction with biological membranes. Shows potential in photodynamic therapy and light-harvesting systems because of its extended conjugation and photoresponsive behavior.
