Used primarily as a ligand in coordination chemistry, this compound forms stable complexes with various metal ions, particularly transition metals. These complexes are often employed in the development of organic light-emitting diodes (OLEDs) due to their ability to enhance electroluminescence efficiency. Additionally, it serves as a key component in the synthesis of photoluminescent materials, which are utilized in sensors and imaging technologies. It is also widely used in analytical chemistry for the spectrophotometric determination of metal ions, such as iron(II), forming intensely colored complexes with high sensitivity and selectivity, particularly for environmental monitoring of heavy metals. Its role in catalytic processes is noteworthy, where it aids in facilitating specific chemical reactions, particularly in organic synthesis. Furthermore, it is explored in the field of supramolecular chemistry for constructing complex molecular architectures.
