Embodiment

[0226] A) Synthesis Examples

[0227] Unless otherwise specified, the following syntheses were carried out in dry solvents under a protective gas atmosphere. The compounds of the present invention can be prepared by means of synthetic methods known to those of ordinary skill in the art.

[0228] Raw materials that can be used are, for example, 3-(bromophenyl)-1-phenyl-2-propen-1-one (Chemistry & Biodiversity, 2005, 2(12), 1656-1664), 2-(3-bromophenyl) )-4,6-diphenylpyrimidine, 4-(3-bromophenyl)-4,6-diphenylpyrimidine (WO2005 / 085387) and 9,10-dihydro-9,9'-dimethyl Acridine (Chem. Ber. 1980, 113(1), 358-384).

[0229] I) Synthesis of intermediate 1a and analogous compounds 2a-9a

[0230] step 1:

[0231]

[0232] 149 g (687 mmol) of methyl 2-bromobenzoate and 100 g (784 mmol) of 4-chloroaniline were dissolved in 1500 ml of toluene and degassed by introducing an inert gas. Then 271 g (825 mmol) of degassed Cs were added 2 CO 3 , 15.4g (69mmol) Pd(OAc) 2 and 13.9 g (23 ...

Abstract

The present application relates to a compound with a formula (I), the use of this compound in an electronic device, and an electronic device containing one or more compounds of the formula (I). Furthermore, the invention relates to the manufacture of the compound with the formula (I) and to a formulation containing one or more compounds with the formula (I).

Description

technical field [0001] The present invention relates to compounds of formula (I), to the use of such compounds in electronic devices, and to electronic devices comprising one or more compounds of formula (I). The present invention also relates to the preparation of compounds of formula (I), and to formulations comprising one or more compounds of formula (I). Background technique [0002] The development of novel functional compounds for use in electronic devices is currently the subject of intense research. The aim here is to develop and investigate compounds that have hitherto not been used in electronic devices, and to develop compounds that can improve the distribution of device properties. [0003] According to the present invention, the term electronic device is especially taken to mean organic integrated circuits (OICs), organic field effect transistors (OFETs), organic thin film transistors (OTFTs), organic light emitting transistors (OLETs), organic solar cells (OSC...
