Used as an intermediate in the synthesis of organic semiconductors and optoelectronic materials. It plays a key role in the preparation of conjugated polymers and small molecules for applications in organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its hydrazone functionality allows for further chemical modifications, enabling fine-tuning of electronic properties. Also explored in the development of fluorescent sensors and dyes due to its extended π-conjugation and ability to undergo intramolecular charge transfer.
