Used in organic electronics as a ligand in the synthesis of luminescent metal complexes, particularly for iridium and platinum-based OLED emitters. Its structure supports efficient electron transport and enhances emission efficiency in light-emitting diodes. Also investigated for use in fluorescent sensors due to its strong chelating ability and tunable emission properties. Shows potential in biological imaging applications owing to its cell permeability and low cytotoxicity when complexed with certain metals.
