Used primarily in the synthesis of high-performance organic semiconductors and pigments. It serves as a key building block in the production of n-type organic semiconductors for use in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its rigid, planar structure enhances electron transport and promotes strong π-π stacking, improving device efficiency. Also employed in the preparation of naphthalene diimide dyes, which are valued for their thermal stability, intense color, and applications in solar cells and fluorescent sensors. Additionally, it finds use in the development of metal-organic frameworks (MOFs) and functional polymers with high thermal and chemical resistance.
