ABSTRACT:
A conjugated polymer in an oxidized state has a doping level of 0.4 or higher. In said oxidized state the polymer is electroconductive, transparent to visible light and preferably colorless. A method of preparing such a polymer comprises the step of bringing the polymer into contact with a strong oxidative agent such as thianthrenium perchlorate. Layers of such polymers may be used as a transparent coating on a display device or as an electrode layer in an electroluminescent device.
