Used as a key intermediate in the synthesis of functional organic materials, particularly in the development of liquid crystals and conjugated polymers. Its aldehyde groups allow for easy modification via condensation reactions, making it valuable in constructing Schiff bases and other imine-based structures for optoelectronic applications. Also employed in the preparation of porous organic frameworks and covalent organic frameworks (COFs), where its rigid aromatic core and extended alkoxy chains contribute to framework stability and porosity. The compound’s solubility, enhanced by the pentyloxy side chains, facilitates solution-processing in thin-film device fabrication, useful in sensors and organic electronics.
