With hydrophobic backbone and hydrophilic side chains, PFN-Br (CAS number 889672-99-5) is a conjugated polymer electrolyte (CPE). It serves as an electron-interface layer material in organic electronic devices (including OFET, OLED, OPV and perovskite solar cells) to improve the interfacial properties such as extraction efficiency.

PFN-Br interfacial layer embedded in OPV devices gives overall enhanced open-circuit voltage, short-circuit current density and fill factor thus improved device performance. It is also believed that the device performance of polymer LEDs with bilayer cathodes (e.g. PFN-Br/Al), can be enhanced to levels comparable to (and even higher than) those obtained from using Ca or Ba cathodes due to its strong polar ionic pendant groups.
