Used in organic synthesis for Suzuki-Miyaura cross-coupling reactions to construct biaryl frameworks, which are common in pharmaceuticals and advanced materials. Its pyrene moiety provides strong fluorescence, making it useful as a fluorescent probe or label in sensors and bioimaging applications. The boronic acid group binds diols, enabling its use in detecting sugars, nucleotides, and other biologically relevant molecules. Also employed in the development of conjugated polymers and organic electronic materials due to the extended π-system from pyrene. Common in research settings for fabricating fluorescent sensors and studying molecular recognition events.
