Used as a key intermediate in the synthesis of high-performance organic semiconductors and optoelectronic materials. Its rigid conjugated structure enhances charge transport properties, making it suitable for applications in organic field-effect transistors (OFETs) and photovoltaic devices. Commonly employed in the development of fluorescent sensors due to its ability to undergo intramolecular charge transfer upon binding with metal ions or anions. Also utilized in coordination chemistry to form stable complexes with transition metals, which are explored for catalytic and luminescent applications. Shows potential in supramolecular chemistry for constructing functional self-assembled systems driven by hydrogen bonding and π–π interactions.
