Abstract
The invention relates to conductive polymer composites comprising a first layer comprising at least one electrically doped conductive polymer and a second layer comprising at least one material selected from a colloid-forming polymeric acid, a salt of a colloid-forming polymeric acid, a non-polymeric fluorinated organic acid, and a salt of a non-polymeric fluorinated organic acid.
Claims16
An electronic device comprising an anode, a buffer layer, and an active organic material layer, wherein the buffer layer is a composite comprising a first layer comprising at least one doped conductive polymer and a second layer comprising a material selected from a colloid-forming polymeric acid, a salt of a colloid-forming polymeric acid, a non-polymeric fluorinated organic acid, and a salt of a non-polymeric fluorinated organic acid, wherein the composition of the first layer and the second layer is different, and further wherein at least one additional layer is interposed between the first layer and the second layer.
An organic light-emitting diode comprising an anode, a buffer layer, an electroluminescent layer, and a cathode, wherein the buffer layer is a composite comprising a first layer comprising at least one doped conductive polymer and a second layer comprising a material selected from a colloid-forming polymeric acid, a salt of a colloid-forming polymeric acid, a non-polymeric fluorinated organic acid, and a salt of a non-polymeric fluorinated organic acid, wherein the composition of the first layer and the second layer is different, and further wherein at least one additional layer is interposed between the first layer and the second layer.
