p-doped organic hole conductor crosslinking

The present invention relates to methods for the preparation hole conducting electrical layers in which a functionalized organic matrix compound is contacted with at least one crosslinking agent on a substrate to form higher molecular weight compounds to the reaction, wherein the functionalized organic matrix compound of the following formula 1 corresponds to, wherein L is a bond or is selected from the group comprising substituted or unsubstituted, saturated or unsaturated C1-C50 alkyl, aryl, polyethylene glycol, Polyethylendiamin-, polyester, polyurethane, Polyvinylidenphenyl chains or mixtures thereof; E R is selected from the group consisting of H, D, C1-C10 alkyl or aryl silyl esters, fluorinated or non-fluorinated, branched or unbranched C1-C10 alkyl, aryl or heteroaryl, R
