Water soluble conjugated polymers can be spin-coated on organic soluble conjugated polymers, when organic soluble blue and red, and water soluble green emission polymer were used as multi-layer device, WPLEDs can be produce by the total color of self emission at multi-layer. Water soluble anionic poly(9,9-bis(4´-sulfonatobutyl)fluorene-co-alt-1,4-phenylene) (anionic-PFP) was synthesized, and we investigated the white color emission by multi-layer of this class of anionic conjugated polyelectrolytes and organic conjugated polymers (MEH-PPVs) using the device structure: ITO/PEDOT:PSS/anionic PFP/MEH-PPV/Al, because anionic PFP can get the self-blue emission and green emission by aggregation effect in film condition. Finally, the color of devices made using different device structure of ITO/PEDOT:PSS/MEH-PPV/anionic PFP/Al was compared, and this device can get the blue and red emission because the green emission of anionic PFP was absorbed in MEH-PPV. |
