Embodiment

[0173] A) Synthesis Example

[0174] The following syntheses were carried out in dry solvents under a protective gas atmosphere unless otherwise indicated. The raw materials or reactants that can be used are, for example, 3,4-dimethylpyrrolo[3,4-b]indole-3,4(2H)-dicarboxylate (Science of Synthesis 2002, 9441-552), 2- (3-bromophenyl)-4,6-diphenylpyrimidine, 4-(3-bromophenyl)-4,6-diphenylpyrimidine, 4-(3,5-dibromophenyl)-4 , 6-diphenylpyrimidine (WO2005 / 085387) and 2-(3,5-dibromophenyl)-4,6-diphenylpyrimidine.

[0175] Example compound 1

[0176] a) Diethyl 2-phenyl-2H-pyrrolo[3,4-b]indole-3,4-dicarboxylate

[0177]

[0178] 53 g (176 mmol) of diethyl pyrrolo[3,4-b]indole-3,4(2H)-dicarboxylate and 129 g (1059 mmol) of phenylboronic acid were dissolved in 2000 ml of dichloromethane and degassed. 71 ml of triarylamine and 40 g (356 mmol) of copper(II) acetate and 111 g of molecular sieves (0.4 NM) were added. The reaction mixture was then stirred at room temperature for 80...

Abstract

The present invention relates to compounds of formula (I), (II) or (III), to the use of said compounds in electronic devices, and to compounds comprising one or more formulas (I), (II) or (III) of electronic devices. The invention also relates to processes for the preparation of compounds of formula (I), (II) or (III), and to formulations comprising one or more compounds of formula (I), (II) or (III).

Description

technical field [0001] The present invention relates to compounds of formula (I), (II) or (III), to the use of said compounds in electronic devices, and to compounds comprising one or more of formula (I), (II) or (III) of electronic devices. The invention also relates to processes for the preparation of compounds of formula (I), (II) or (III), and to formulations comprising one or more compounds of formula (I), (II) or (III). Background technique [0002] Organic semiconducting materials, such as the compounds according to the invention, are being developed for many different applications in electronic devices. The structures of organic electroluminescent devices (OLEDs) in which the compounds according to the invention can be used as functional materials are described, for example, in US Pat. [0003] Especially considering the wide commercial use, further improvements are still needed in terms of the performance data of organic electroluminescent devices. Of particular ...
