Used as a key building block in the synthesis of metal-organic frameworks (MOFs), particularly for applications in gas storage, separation, and catalysis. Its rigid aromatic structure and nitrogen-containing pyridyl group enhance coordination with metal ions, improving framework stability and porosity. Also employed in the development of luminescent sensors due to its ability to chelate lanthanide ions and exhibit fluorescence properties. Additionally, it finds use in constructing porous materials for drug delivery and environmental remediation, such as the removal of heavy metals or organic pollutants from water.
