2,2'-(9,9-dioctyl-9H-fluorene-2,7-diyl)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane), CAS number 196207-58-6, is a precursor for the synthesis of polymer semiconductors in the application of OLED, PLED, OFET and Polymer Solar Cells.

With their pure blue and efficient electroluminescence, high charge-carrier mobility and good processability, alkylated polyfluorene conjugated polymer semiconducting materials have attracted great research and industrial interests --  especially for display technology photovoltaic applications. PFN, a fluorene back-boned polymer semiconductor, is a conjugated polyelectrolyte embedded between the cathode and the active layer in OPV devices to improve electron extraction efficiencies. Both PFO (F8) and F8BT use the same polyfluorene sub unit, and can be blended to make a high-efficiency green OLED. F8BT calso used as an acceptor for polymer blends devices.
