Abstract
Abstract Mixtures of A) neutral polythiophenes of formula (I), <IMAGE> wherein R1 and R2 separately from one another represent hydrogen or a C1-4 alkyl group or together form an optionally substituted C1-4 alkylene radical, preferably a methylene radical optionally substituted by alkyl groups, an ethylene-1,2 radical optionally substituted by C1-12 alkyl or phenyl groups, or a cyclohexylene-1,2 radical, and B) organic compounds containing dihydroxy or polyhydroxy and/or carboxyl groups or amide groups or lactam groups, as well as transparent, electrically conducting coatings made therefrom and electroluminescent systems containing a conductive layer produced from the abovementioned mixtures as the electrode.
