Used primarily in the field of coordination chemistry, this compound serves as a versatile ligand for the synthesis of metal-organic frameworks (MOFs) and coordination polymers. Its tridentate structure allows it to bind effectively with various metal ions, facilitating the creation of complex architectures with potential applications in catalysis, gas storage, and separation processes. Additionally, it is employed in the development of luminescent materials due to its ability to form stable complexes with lanthanides and transition metals, which are useful in optoelectronic devices. Its carboxylic acid groups further enhance its utility by enabling functionalization and modification for targeted applications.
