簡單介紹：
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.

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,
| EL Polymer | Cathode | Luminance (cd m -2) | QE (%) | LE (Cd A-1) |
| MEH-PPV | Al | 6 | 0.02 | 0.02 |
| MEH-PPV | Ba/Al | 749 | 2.46 | 2.1 |
| MEH-PPV | PNF-I/Al | 773 | 2.85 | 2.4 |
