The invention relates to polymers having at least one repeating unit of the following formula (I): wherein Ar, Ar, Arand Ar, R and X, and a, b, c, d, e and f can have the meanings defined in claim, to processes for the preparation thereof and to the use thereof in electronic or optoelectronic devices, in particular in organic electroluminescent devices, so-called OLEDs (OLED═Organic Light Emitting Diodes). The present invention also relates to electronic or optoelectronic devices, in particular organic electroluminescent devices, which contain said polymers.

Polymers with amine-group-containing repeating units

The present invention relates to compounds of formula (1). The compounds are suitable for use in electronic devices, in particular organic electroluminescent devices, comprising these compounds. In some embodiments, the compounds are used as matrix materials for phosphorescent or fluorescent emitters as well as a hole-blocking or electron-transport materials. 

Materials for organic electroluminescent devices

The present application relates to a blue light-emitting organic electroluminescent device (OLED) having an anode, a cathode, at least one blue light-emitting layer and at least one hole-transport layer, wherein the at least one blue light-emitting layer comprises an elongated bis-indenofluorene derivative as a main component and wherein the at least one hole-transport layer comprises a polymer with non-conjugated units as a main component as well as to a method for producing the organic electroluminescent device.

Organic electroluminescent device

The present application relates to a polymer containing at least one structural unit of a formula (I). The polymer is suitable for use in an electronic device.

Materials for electronic devices

The present application relates to a polymer containing at least one structural unit of a formula (I) and at least one further structural unit selected from structural units A, B and C. The present application further relates to the use of the polymer in an electronic device and to a process for preparing the polymer. The present application further relates to an electronic device comprising the polymer.

Described herein is a process for the preparation of an electronic device such as an organic electroluminescent device (OLED), wherein two adjacent functional layers having an interface are formed from solution in a kinetically controlled manner. The process is particularly suitable for fast and efficient production of electronic devices by printing or coating processes. The description further relates to an electronic device which is obtainable by said process.

Process for making electronic device

The present invention relates to compositions comprising at least one polymer which contains triarylamine repeating units, and at least one metal complex, to 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 compositions.

Compositions comprising at least one polymer and at least one metal complex and to electroluminescent devices containing said compositions

The present invention relates to formulations which comprise at least one organic semiconductor, at least one metal complex and at least one solvent and the use of these formulations in electronic devices, in particular organic electroluminescent devices.
