摘要

The present invention relates to compounds of the general formula (I) wherein Z corresponds a to — a C₁-C₂₂-alkyl radical substituted by halogen, phosphonic acid or phosphonic acid ester groups —P(O)(OR¹)₂ (wherein the radicals R¹ can be identical or different and correspond to a hydrogen atom or C₁-C₁₂-alkyl), sulphonic acid groups —SO₃H, halosilyl radicals —SiHal_nR²_3−n(R²═C₁-C₁₈-alkyl, n=an integer from 1 to 3), thiol groups or trialkoxysilyl radicals —Si(OR³)₃ (R³═C₁-C₁₈-alkyl), — a C₅-C₁₂-cycloalkyl radical substituted by halogen, phosphonic acid or phosphonic acid ester groups—P(O) (OR¹)₂ (wherein the radicals R¹ can be identical or different and correspond to a hydrogen atom or C₁-C₁₂-alkyl), sulphonic acid groups —SO₃H, halosilyl radicals —SiHal_−nR²_3−n(R²═C₁-C₁₈-alkyl, n=an integer from 1 to 3), thiol groups or trialkoxysilyl radicals —Si(OR³)₃ (R³═C₁-C₁₈-alkyl), — a C₆-C₁₄-aryl radical or heteroaryl radical from the group of the thienyl, pyrryl, furyl or pyridyl radicals substituted by halogen, phosphonic acid or phosphonic acid ester groups —P(O)(OR¹)₂ (wherein the radicals R¹ can be identical or different and correspond to a hydrogen atom or C₁-C₁₂-alkyl), sulphonic acid groups —SO₃H, halosilyl radicals —SiHal_nR²_3−n (R²═C₁-C₁₈-alkyl, n=an integer from 1 to 3), thiol groups or trialkoxysilyl radicals —Si(OR³)₃ (R³═C₁-C₁₈-alkyl), or — a C₇-C₃₀-aralkyl radical optionally substituted by halogen, phosphonic acid or phosphonic acid ester groups —P(O)(OR¹)₂ (wherein the radicals R¹ can be identical or different and correspond to a hydrogen atom or C₁-C₁₂-alkyl), sulphonic acid groups —SO₃H, halosilyl radicals —SiHal_nR²_3−n (R²═C₁-C₁₈-alkyl, n=an integer from 1 to 3), thiol groups or trialkoxysilyl radicals —Si(OR³)₃ (R³═C₁-C₁₈-alkyl) or a trialkylsilyl radical R⁵R⁶R⁷Si, in which R⁵, R⁶, R⁷ independently of each other are identical or different C₁-C₁₈-alkyl radicals. The present invention also relates to a semiconductor layer, an electronic component, a process for the production of an electronic component, the electronic component obtainable by this process and the use of compounds of the general formula (I).;
