Used primarily in organic synthesis as a boronic ester building block for Suzuki-Miyaura cross-coupling reactions. Enables the formation of biaryl and extended aromatic systems commonly found in organic semiconductors and liquid crystal materials. Frequently employed in the development of conjugated polymers for organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its hexyloxy side chains enhance solubility in organic solvents, facilitating solution-based processing in thin-film device fabrication. Also applied in the synthesis of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) where controlled molecular geometry and boron-based reactivity are required.
