Used as a key intermediate in organic synthesis, particularly in the development of organic semiconductors and optoelectronic materials. Its rigid, conjugated structure enhances electron delocalization, making it valuable in organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Frequently incorporated into polymer backbones or as a core unit in small molecule emitters to improve thermal stability and charge transport properties. Also explored in sensor applications due to its fluorescence response to specific analytes.
