Applications

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

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