2,7-Dibromo-9,9′-spiro-bifluorene(CAT: M044897) is a brominated spirobifluorene derivative widely used as a key intermediate in the synthesis of organic semiconductors and optoelectronic materials. Featuring a rigid spiro-linked fluorene core and bromine substituents at the 2 and 7 positions, it offers excellent thermal stability and molecular rigidity—ideal for constructing conjugated polymers and small molecules with well-defined electronic properties. This compound is commonly employed in the development of OLEDs, OFETs, and photovoltaic devices, where its architecture supports high charge mobility and morphological stability. The reactive bromo groups facilitate further functionalization via cross-coupling reactions.
