Used as a key intermediate in the synthesis of functional organic materials, particularly in the development of conjugated polymers and dyes. Its rigid aromatic structure and carboxylic acid groups allow for strong intermolecular interactions and easy functionalization, making it suitable for applications in organic electronics such as organic field-effect transistors (OFETs) and dye-sensitized solar cells. Also employed in the preparation of metal-organic frameworks (MOFs) due to its ability to chelate metal ions, contributing to the design of porous materials for catalysis or gas storage. Its quinone functionality enables redox activity, useful in electroactive compounds and energy storage systems.
