The water soluble green emission polymer of WPLEDs were used as multi-layer device. This WPLEDs can be produced by total color of self emission at multi-layer. Water soluble anionic poly(9,9-bis(4-sulfonatobutyl)fluorene-co-alt-1,4-phenylene)(anion-PF(Na+)) was synthesized, and we investigated the white color emission by multi-layer of this class of anionic conjugated polyelectrolytes and MEH-PPV using the following device structure: ITO/PEDOT:PSS/anion-PF(Na+)/MEH-PPV/Al, because anionic PFP can get the self-blue 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/anion-PF(Na+)/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. |
