| 摘要 |
The present invention relates to n-dopants for increasing the electronic conductivity of organic electrical layers, wherein the n-dopant is selected from the group comprising heterocyclic alkali metal salts of the following formula I where X1 - X5 are independently selected from the group comprising -CH2-, -CHR-, -CR2-, -C(=O)-, - (C=S) -, - (C=CR2) -, - C(CR)-, =CH-, =CR-, -NH-, -NR-, =N-, -O-, -S-, -Se-, -P(H)-, -P(R)-, -N--, =C--, -CH--, -CR--, -P--, where at least one Xi provides a heteroatom in the five-membered ring and the ring is formally negatively charged; R is independently selected from the group comprising -H, -D, halogen, -CN, -NO2, -OH, amine, ether, thioether, ester, amide, C1-C50 alkyl, cycloalkyl, acryloyl, vinyl, allyl, aromatic system, fused aromatic system, heteroaromatic system; M = alkali metal or alkaline earth metal and n = 1 or 2. |
