PFN-FP-I is the diiodide salt of the polyfluorene PFN-FP, a conjugated polymer electrolyte (CAS 1026670-72-3) from Ossila. This catalogue entry covers batch M2080A1, which has an Mw of 21 kDa, an Mn of 9.5 kDa and a PDI of 2.2.
The material serves two purposes in device fabrication. It can be the emissive active layer in blue OLEDs. It can also be used as an electron-interface layer, or cathode interlayer, in OLEDs, organic photovoltaics and perovskite solar cells, where it helps improve extraction efficiency.
Its strongly polar ionic pendant groups make PFN-FP-I soluble in methanol and water. It also dissolves in polar solvents that contain a small amount of acetic acid. This lets it be processed from solution in solvents that are orthogonal to those used for many other organic layers.
- Active layer material in blue organic light-emitting diodes.
