[0139] Synthesis of ArL group
[0140] Synthesis of compound Int1.1
[0141]
[0142] 30g (97.5mmol) of 2-bromo-7-chloro-9,9-dimethyl-9H-fluorene (see JP 2003277305 A), 25.5g (107.3mmol) of (9,9-dimethylfluorene-2- Base) boronic acid 90g (390mmol), 0.9g (4mmol) palladium (II) acetate and 3.6g (11.7mmol) tri (o-tolyl) phosphine in 1L toluene, di Mix in alkane and water (1:1:1) and stir at reflux overnight. After cooling to room temperature, 200 mL of toluene was added, the organic phase was separated and washed with water (2 x 200 mL), and the combined organic phases were concentrated under reduced pressure. The residue was purified by recrystallization from toluene / heptane.
[0143] Yield: 39.1 g (93 mmol; 96%).
[0144] The following compounds can be synthesized in a similar manner:
[0196] The substrate pretreatment of embodiment V1, E1 to E8:
[0197] A glass plate with structured ITO (50nm, indiumtinoxide) was coated with 20nm PEDOT:PSS (poly(3,4-ethylenedioxythiophene), poly(styrene-sulfonate, CLEVIOS TM P VP AI 4083, from Heraeus Precious Metals GmbH, Germany, was spin-coated from a water-based solution) as a buffer layer to form the substrate on which the OLED device was fabricated.
[0198] The OLED device basically has the following layer structure:
[0209] The cathode was formed from an aluminum layer with a thickness of 100 nm. The detailed stack sequence is shown in Table A. Table C shows the materials ...

Abstract
The invention relates to a material for an organic electroluminescence device. Specifically, the invention relates to a formula (1) compound suitable for an electronic device, particularly an organicelectroluminescence device, and an electronic device containing the compounds.
Description
technical field [0001] The invention relates to a material for organic electroluminescent devices. In particular, the present invention relates to compounds of formula (1), their use in electronic devices and electronic devices comprising compounds of formula (1). The invention also relates to processes for the preparation of compounds of formula (1) and formulations comprising one or more compounds of formula (1). Background technique [0002] The development of functional compounds for use in electronic devices is the subject of intense current research. The aim is in particular to develop compounds with which improvements in the properties of electronic devices can be achieved at one or more relevant points, for example in the power efficiency and lifetime of the devices and in the color coordinates of the emitted light. [0003] According to the present invention, the term electronic device is considered to mean, inter alia, organic integrated circuits (OICs), organic ...
