Used as a fluorescent probe in biochemical assays due to its strong emission upon binding to specific metal ions. It is particularly effective in detecting zinc and copper in biological systems, offering high sensitivity and selectivity. Also employed in the development of sensors for environmental monitoring, where it helps trace heavy metal contamination in water and soil. Its rigid structure makes it suitable for incorporation into supramolecular assemblies and coordination polymers used in material science. Additionally, it serves as a ligand in catalytic systems, enhancing the stability and activity of metal catalysts in organic transformations. Furthermore, it is utilized in functional materials research, particularly in electron transfer systems and optoelectronic devices such as lasers and light-emitting diodes, due to its multi-nitrogen coordination sites that bind transition metals effectively.
