Used as a key intermediate in the synthesis of organic semiconductors and conjugated polymers for optoelectronic devices. Commonly applied in the development of organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs) due to its strong electron-donating properties and good charge transport characteristics. Its structure supports efficient π-conjugation, enhancing device performance. Also employed in the preparation of fluorescent dyes and sensors for detecting metal ions or biological molecules. Suitable for solution-processing techniques, making it valuable in fabricating flexible and low-cost electronic devices.
