Used as a key building block in the synthesis of metal-organic frameworks (MOFs), particularly for constructing porous materials with high thermal stability. Its rigid aromatic structure and multiple coordination sites enable the formation of extended networks useful in gas storage, separation, and catalysis. Also employed in the development of luminescent materials and sensors due to its ability to chelate metal ions and enhance photophysical properties. Shows potential in optoelectronic applications when incorporated into organic semiconductors.
