Used as a key building block in the synthesis of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), this compound provides rigid, conjugated linkages that enhance framework stability and porosity. Its carboxylic acid groups allow strong coordination with metal ions, making it ideal for constructing porous materials used in gas storage, catalysis, and chemical sensing. The extended π-conjugated system also supports electronic applications, such as in organic semiconductors or optoelectronic devices. Additionally, it serves in the design of luminescent sensors due to its ability to host guest molecules and facilitate energy transfer.
