Applications

PFN-I is the diiodide salt of PFN, and is a conjugated polymer electrolyte (CPE). It is commonly used as an electron-interface layer material in organic electronic devices (including OLED, OPV and perovskite solar cells) to improve extraction efficiency. PFN-I is also used as an active layer material for blue OLED devices.

It is believed that the device performance of polymer LEDs with bilayer cathodes (such as. PFN-I/Al), can be enhanced to levels comparable to (and even higher than) those obtained from using Ca or Ba cathodes [1].

Due to its strong polar ionic pendant groups, PFN-I is soluble in methanol and water,
