Used primarily in the synthesis of high-performance polyimides, organic semiconductors, and pigments. It serves as a key building block in the production of n-type organic semiconductors, such as naphthalene diimides (NDIs), for applications in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs) due to its strong electron-accepting properties. Its rigid, planar structure enhances π-π stacking, improving charge carrier mobility in thin-film devices. Also employed in the preparation of naphthalene diimide dyes, which exhibit excellent thermal and photochemical stability, making them suitable for use in dyes, fluorescent probes, and advanced coatings. Additionally, it is a key precursor for high-temperature resistant polyimide resins used in electronics, aerospace, and components operating in harsh environments. It also finds use in coordination chemistry as a ligand for metal-organic frameworks (MOFs) with tailored electronic and optical properties.
