Used as a precursor in the synthesis of high-performance organic semiconductors and n-type organic dyes. Its rigid, planar structure and electron-deficient core make it ideal for constructing π-conjugated systems in organic electronics, such as organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Also employed in the development of fluorescent probes and sensors due to its strong electron-accepting properties and stability. Commonly utilized in the preparation of perylene diimide analogs, which exhibit excellent thermal and oxidative stability, useful in optoelectronic devices and as building blocks for supramolecular architectures.
