Used as a key intermediate in the synthesis of conjugated organic semiconductors, particularly in the development of high-performance organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its rigid, planar structure enhances π-π stacking and promotes charge carrier mobility in thin-film devices. Commonly employed in donor-acceptor type polymers and small molecules for optoelectronic applications due to strong intermolecular interactions and tunable electronic properties. Also utilized in the preparation of covalent organic frameworks (COFs) for sensing and catalysis owing to its well-defined geometry and functional aldehyde groups.
