Used as a key intermediate in the synthesis of conjugated organic materials for optoelectronic devices. It serves in the preparation of fluorescent dyes and organic semiconductors due to its extended π-conjugated structure. Commonly employed in the development of organic light-emitting diodes (OLEDs) and sensors, where its rigid, planar framework enhances electron delocalization and luminescence properties. Also utilized in research for constructing metal-organic frameworks (MOFs) with tunable emission behavior.
