Used as a key building block in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to construct conjugated organic materials. It enables the formation of carbon-carbon bonds, making it valuable in the development of organic semiconductors, conductive polymers, and optoelectronic materials such as OLEDs and organic photovoltaics. Its boronate ester groups provide high stability and reactivity, facilitating efficient coupling under mild conditions. Also employed in the synthesis of functional dyes and fluorescent probes due to the pyrrole core’s electron-rich nature.
