Used as a fluorescent probe in biochemical assays due to its strong emission properties in organic solvents. It selectively binds to folded DNA structures, making it useful in studying G-quadruplex formations in genetic research. Also applied in photophysical studies for developing organic light-emitting diode (OLED) materials because of its thermal stability and efficient luminescence. Serves as a ligand in catalytic metal complexes for asymmetric synthesis in pharmaceutical intermediates.
