2,2′-(9,9-Dioctyl-9H-fluorene-2,7-diyl)bis(1,3,2-dioxaborinane)(CAT: L018675) is a boron-containing fluorene derivative bearing two 1,3,2-dioxaborinane moieties at the 2 and 7 positions and long dioctyl alkyl chains at the 9-position. This compound serves as a highly functionalized boronic ester monomer in Suzuki–Miyaura cross-coupling reactions, making it ideal for constructing conjugated polymers and π-electron-rich materials. The fluorene core imparts excellent thermal stability, optical properties, and charge-transport behavior, while the bulky dioctyl chains enhance solubility and film-forming ability. It is commonly used in the development of OLEDs, OFETs, and photovoltaic devices, enabling fine-tuned optoelectronic performance in organic electronic applications.
