Used as a fluorescent probe in biochemical assays due to its ability to intercalate with aromatic systems and exhibit changes in emission upon binding. Employed in the study of protein-ligand interactions, especially with DNA-binding proteins, where it acts as a competitive binder in intercalation sites. Also utilized in organic electronics as a dopant to modify charge transport properties in thin-film semiconductors. Its rigid, planar structure supports use in supramolecular chemistry for designing molecular sensors and switches.
