Abstract
Recently, the novel organic materials for white OLEDs have been researched, but it is not easy to apply polymers to WPLEDs. However, because water soluble conjugated polymers can be spin-coated on organic soluble conjugated polymers, when organic soluble blue and red emission polymers, 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) (anion-PF(Na+)) was synthesized, and we investigated the white color emission by multi-layer of this class of anionic conjugated polyelectrolytes and organic conjugated polymers (MEH-PPV) using the following device structure: ITO/PEDOT: PSS/anion-PF(Na+)/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/MEHPPV/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.
