preparation example Construction

[0032] The present invention also provides a method for preparing the anthracene-containing derivatives, which comprises the following steps:

[0033] Step S1: adding an anthracene bromine-substituted compound and a boronic acid compound containing a substituent R to the reaction system;

[0034] Step S2: degassing the reaction system, and then adding a catalyst;

[0035] Step S3: Elevate the reaction temperature of the reaction system and reflux to fully react to obtain the anthracene-containing derivatives.

Embodiment 1

[0037] In order to illustrate the preparation method in the present invention in more detail, the anthracene-containing derivatives designated as 31 below As an example to describe. Its specific reaction equation is shown in formula 1.

[0038] Formula 1

[0039]

[0040] Under nitrogen protection, add compound [31-1] 50g (103.00mmol) in formula 1 to 2L reactor, compound [31-2] 41.79g (133.90mmol), K 2 CO 3 22.77g (164.80mmol), stirred with 500mL of toluene. And when the temperature in the reactor was raised to 70° C., 3.57 g (3.09 mmol) of catalyst tetrakis(triphenylphosphine) palladium was added, and 75 mL of distilled water was added and stirred for 11 hours. Add 70mL of water to end the reaction, filter under reduced pressure to obtain the crude product of the target derivative, wash three times with distilled water, then recrystallize with acetone, toluene, tetrahydrofuran solution to obtain a solid, then sublimate and refine it, and recrystallize toluene to obtai...

Abstract

The invention discloses an anthracene containing derivative as well as a preparation method and an application thereof. The molecule general formula of the anthracene containing derivative is as shown in specification, wherein R is an aromatic heterocyclic radical or a heteroatomic compound substituent, the carbon atom number of which is 5-32. The anthracene containing derivative has high luminous efficiency; the high luminous efficiency shows that the compound can serve as a luminescent material or a luminescent host material, particularly can serve as a phosphorescence green host material to be applied to an organic light-emitting device and is relatively low in preparation cost; due to the adoption of the anthracene containing derivative, the service life of the organic electroluminescence device is prolonged, and the manufacturing cost of the organic electroluminescence device is reduced.

Description

technical field [0001] The invention relates to the field of organic photoelectric materials, in particular to an anthracene-containing derivative, a preparation method and an application thereof. Background technique [0002] Organic electroluminescence generally consists of two opposing electrodes and at least one layer of organic light-emitting compound interposed between the two electrodes. Charges are injected into the organic layer formed between the anode and cathode to form electron and hole pairs, which cause light emission from organic compounds having fluorescent or phosphorescent properties. [0003] The research on organic electroluminescent materials was observed in 1950 when Bernose applied high current and voltage to polymer films containing organic pigments. In 1965, Pope et al. first discovered the electroluminescent properties of anthracene single crystals, which is the first electroluminescent phenomenon of organic compounds. [0004] In order to make h...
