Atomfair 2,7-Dibromo-9,9-dibutyl-9H-fluorene C21H24Br2

Description 2,7-Dibromo-9,9-dibutyl-9H-fluorene (CAS No. 188200-91-1) is a high-purity brominated fluorene derivative with the molecular formula C21H24Br2. This compound is a valuable building block in organic synthesis, particularly in the development of conjugated polymers, organic semiconductors, and optoelectronic materials. Its rigid fluorene core and dibromo substitution at the 2,7-positions make it an ideal precursor for Suzuki, Stille, or other cross-coupling reactions to construct extended ??-systems. The dibutyl groups at the 9-position enhance solubility in common organic solvents, facilitating processing for thin-film applications. This product is meticulously synthesized and purified to ensure >98% purity (HPLC), as confirmed by GC-MS and1H/13C NMR spectroscopy.…

Application

2,7-Dibromo-9,9-dibutyl-9H-fluorene serves as a key monomer in the synthesis of polyfluorenes, a class of blue-emitting polymers for OLED displays and lighting. Its dibromo functionality enables efficient polymerization via palladium-catalyzed cross-coupling reactions, yielding materials with high charge-carrier mobility for organic thin-film transistors (OTFTs). The compound is also employed in the development of solution-processable small-molecule semiconductors for bulk heterojunction solar cells due to its balanced solubility and optoelectronic properties.
