A method produces cross-linked hole-conducting electric layers by converting functionalized p-dopants. The functionalized p-dopants are organic metal complexes containing at least one central atom and organic ligands, wherein the central atom is selected from a metal of the groups 6-15 of the periodic table, and at least one of the organic ligands is selected from the following formulas I-V, in which E independently of one another is oxygen, sulfur, selenium, or N(E), and each Rhas at least one functionalizing group selected from the group Rincluding &#x2014;OH, &#x2014;COOH, &#x2014;NH, &#x2014;NHR', halogen, C2-C40-alkenyl, -dienyl, -alkinyl, -alkenyloxy, -dienyloxy, -alkinyloxy, acrylic acid, oxetan, oxiran, silane, acrylic acid, anhydride, and cyclobutane or consists of the groups, and G=C(R)HFwhere u+v+w=3 and n=1-4.

Crosslinking p-dopants for p-doping organic hole conductors

The present invention relates to compositions comprising at least one polymer containing repeat triarylamine units and comprising at least one salt, to processes for production thereof and to the use thereof in electronic devices, especially in organic electroluminescent devices, called OLEDs (OLED=organic light-emitting diodes). The present invention also further relates to organic electroluminescent devices comprising these compositions.

Compositions comprising at least one polymer and at least one salt, and electroluminescent devices containing said compositions

The present invention relates to polymers which contain triarylamine repeating units that are substituted in the ortho position, methods for the production thereof, and the use thereof in electronic devices, especially in organic electroluminescent devices, so-called OLEDs (OLED=Organic Light Emitting Diode). The present invention also relates to organic electroluminescent devices which contain said polymers.

Polymers containing substituted triarylamine units and electroluminescent devices containing said polymers

The present invention relates to polymers containing oligo-triarylamine repetition units that are substituted in the ortho position, a method for the production thereof, and use thereof in electronic devices, particularly in organic electroluminescence devices, known as OLEDs (OLED=organic light emitting diodes). The present invention further relates to organic electroluminescence devices containing these polymers.
