Product Description:

4-Vinylphenylboronic acid is an organoboron compound featuring a phenylboronic acid group and a terminal vinyl group. It is a white to off-white crystalline powder that is sensitive to air and moisture, often requiring storage under inert conditions. Its primary and most significant application is as a key monomer and building block in the synthesis of advanced materials. It is extensively used in Suzuki-Miyaura cross-coupling reactions to construct conjugated polymers and small molecules for organic electronics. Specifically, it serves as a crucial precursor for the fabrication of organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and other organic semiconductor devices. The vinyl group allows for further polymerization or functionalization, enabling the creation of materials with tailored electronic and optical properties. Beyond its role in materials science, this compound is also a valuable synthetic intermediate in organic chemistry. The boronic acid moiety facilitates C-C bond formation, making it a versatile reagent for constructing biaryl systems in pharmaceutical and agrochemical research, although its material science applications are dominant.
