Used in the synthesis of liquid crystals and organic semiconductors due to its rigid aromatic structure. Its carboxylic acid group allows for functionalization in polymer formation, particularly in metal-organic frameworks (MOFs) where it acts as a linker ligand. Also employed in photoconductive materials and optoelectronic devices because of its favorable charge transport and luminescent properties. Shows potential in dye-sensitized solar cells and as a building block for supramolecular chemistry through hydrogen bonding interactions.
