Used primarily as a ligand in coordination chemistry, it forms stable complexes with various metal ions, particularly in the synthesis of luminescent materials. Its application extends to organic light-emitting diodes (OLEDs), where it acts as an electron-transport layer, enhancing device efficiency. Additionally, it serves as a key component in the development of sensors and probes for detecting metal ions due to its strong binding affinity and photophysical properties. In catalysis, it is employed in asymmetric synthesis and polymerization reactions, contributing to the production of high-performance polymers. Its role in photovoltaic cells is also notable, where it aids in improving charge transfer and energy conversion efficiency.
