Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions to synthesize conjugated organic materials. Commonly applied in the development of fluorescent dyes and optoelectronic materials due to the benzo[d]thiazole core’s electron-withdrawing nature and strong photoluminescence. Plays a role in constructing sensors for metal ions and biological molecules. Also utilized in the preparation of organic semiconductors for OLEDs and organic photovoltaics, where boron-containing building blocks enhance stability and electronic properties.
