Used as a building block in the synthesis of advanced organic materials, particularly in the development of liquid crystals and organic semiconductors. Its rigid, extended aromatic structure enhances electron delocalization, making it valuable in optoelectronic devices such as OLEDs and organic field-effect transistors (OFETs). Also employed in metal-organic frameworks (MOFs) due to its ability to act as a multitopic linker, contributing to high surface area and porosity for gas storage or catalysis. Its carboxylic acid functionality allows for easy functionalization and integration into larger supramolecular architectures.
