Abstract
An organic electron transport layer has at least one dopant for increasing the n-conductivity of the organic layer. The dopant is selected from the group of salts of cyclopentadiene compounds according to formula 1, wherein the substituents R1 to R2 are independently selected from the group containing —H, -D, halogen, —CN, —NO2, —OH, amine, ether, thioether, alkyl, cycloalkyl, acrylic, vinyl, allyl, aromatics, fused aromatics and heteroaromatics.
Claims10
