Applications

2,2'-(9,9-dioctyl-9H-fluorene-2,7-diyl)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) 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. F8BT, a high efficiency green-yellow emitting luminescent polymer, can also used as an acceptor for polymer blends devices.
