Used in organic synthesis as a boronic ester coupling partner in palladium-catalyzed Suzuki-Miyaura cross-coupling reactions. It enables the formation of carbon-carbon bonds, particularly for extending aromatic systems or building polycyclic frameworks found in organic electronic materials and bioactive molecules. Its chrysene backbone provides a rigid, extended π-conjugated structure, making it valuable in the development of organic semiconductors, OLEDs, and fluorescent dyes. The tetramethylborolane group enhances stability and reactivity under cross-coupling conditions, allowing for efficient functionalization in multi-step syntheses.
