9,9-Dioctyl-2,7-dibromofluorene can be used for the synthesis of polymer semiconductors, engaging either Suzuki coupling or Stille coupling reactions.
Alkyl-substituted polyfluorenes have emerged as a very attractive class of conjugated polymers, especially for display applications. This is due to their pure blue and efficient electroluminescence, coupled with a high charge-carrier mobility and good processability.
Their unique molecular structure, joined biphenyl at 9-position for a maximum pi-conjugation and planar structure, and also their excellent optical and electronic properties altogether have brought semiconducting polyfluorenes to the focus of scientific and industrial interest. Polyfluorenes are known as semiconducting materials used for light emitting diodes, organic photovoltaics and interface layer materials for organic electronics. By reacting with 9,9-Dioctylfluorene-2,7-diboronic acid bis(pinacol) ester in toluene, it yields PFO (F8).
