Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of complex organic molecules, particularly in the development of conjugated materials for organic electronics. Its boronate ester group enables efficient carbon-carbon bond formation, while the silyl-protected alkyne and ether functionalities provide stability and compatibility with multi-step synthetic sequences. Commonly employed in the preparation of organic semiconductors, fluorescent dyes, and liquid crystal materials. The triisopropylsilyl groups act as protective moieties that can be selectively removed under mild conditions, allowing for further functionalization in the construction of extended π-conjugated systems.
