Embodiment

[0225] Synthesis of compounds 1 to 13 of the present invention

[0226] Unless otherwise specified, the following syntheses were carried out under a protective gas atmosphere. Starting materials can be purchased from ALDRICH or ABCR (palladium(II) acetate, tri-o-tolylphosphine, inorganics, solvents). 3-bromofluorenone (Tetrahedron (tetrahedron), 51, 7, 2039-54; 1995) and 3-bromofluorene and the synthesis of bis-biphenyl-4-yl-(4'-bromobiphenyl-4-yl)amine (JP2010-111605).

[0227] Precursor A: 3-bromo-9H-fluorene

[0228]

[0229] To a vigorously stirred and refluxed suspension of 64 g (250 mmol) of 3-bromofluorene in a mixture of 1000 ml of toluene and 2000 ml of ethanol was added 49 ml (1000 mmol) of hydrazine hydrate followed by 3 g of freshly prepared Raney nickel. After reflux for 2 hours, the mixture was cooled, the solvent was removed in vacuo, the residue was dissolved in 1000ml of warm chloroform, the solution was filtered through silica gel, the clear solution wa...

Abstract

The present invention relates to compounds of formula (I), (II) or (III), to the use of said compounds in electronic devices, and to electronic devices comprising compounds of formula (I), (II) or (III). 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 electronic devices comprising compounds of formula (I), (II) or (III). 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] The development of functional compounds for use in electronic devices is the subject of intense current research. The aim here is in particular to develop compounds with which improvements in the properties of electronic devices, such as power efficiency, lifetime or color coordinates of the luminescence, can be obtained at one or more relevant points. [0003] According to the present invention, the term electronic device is in particular taken to mean organic integrated circuits (OICs), organic field-effect transistors (OFETs), organic...
