Title:
DISPERSION, TRANSPARENT ELECTRODE, AND ORGANIC ELECTRO- LUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2011/065213
Kind Code:
A1
Abstract:
A dispersion has been found for the purpose of providing a stable transparent electrode which exhibits excellent smoothness, electroconductivity, and light transmittance, and suffers from little deterioration of smoothness, electroconductivity, or light transmittance even in a high-temperature and high-humidity environment and which can yield a durable organic electroluminescent (EL) element that exhibits excellent uniformity of luminescence and little deterioration of the uniformity. The dispersion is an electroconductive polymer dispersion which contains both a polymer comprising repeating structural units represented by general formula (I) and a polyanion, said electroconductive polymer dispersion being characterized in that the content of sulfate ions is 0 to 300ppm as determined by heating the electroconductive polymer dispersion at 200°C for 60 minutes and then oxidizing the thus-formed sulfur oxides into sulfate ions. In general formula (I), A is optionally substituted C1-4 alkylene, and Q is an oxygen atom or a sulfur atom.
