Abstract
The invention provides an opto-electronic device comprising at least one sulfonated aromatic condensation copolymer or at least one phosphonated aromatic condensation copolymer. The at least one sulfonated aromatic condensation copolymer is selected from sulfonated polyarylethers, sulfonated polyimides, sulfonated polyphenylene oxides, sulfonated polyarylenes, sulfonated polyphosphazenes, and the at least one phosphonated aromatic condensation copolymer is selected from phosphonated polyarylethers, phosphonated polyimides, phosphonated polyphenylene oxides, phosphonated polyarylenes, phosphonated polyphosphazenes and combinations thereof. The sulfonated polyarylether is a sulfonated polyarylether block copolymer having sulfonated polyaryletherketone blocks, sulfonated polyethersulfone blocks, or combinations thereof.
