Embodiment Construction

[0027] In order to better understand the content of the present invention, the technical solutions of the present invention will be further described through specific examples below, but the examples do not limit the present invention.

[0028] Take the preparation of 13,13-dimethyl-3-(2-naphthalene)-13 indeno(1,2-b)anthracene as an example:

[0029] A step reaction:

[0030] 1. Add catalyst to o-xylene, cool to below 5°C, add bromine dropwise, after dropwise addition, react with light for 20 hours, then wash with 5% sodium hydroxide solution and distilled water successively, after washing, distill to get the product o-Dibromotoluene, the yield of this reaction is about 85%.

[0031] 2. Add dichloromethane and concentrated hydrochloric acid to o-dibromotoluene, add methylhydrazine while stirring, and quickly heat up to 50°C after the reactant is completely dissolved, react for 4 hours, then add sodium nitrite dropwise, and distill to obtain Dry 1-methylisoindole.

Abstract

The invention belongs to the technical field of organic electroluminescence, and relates to a blue organic electroluminescence material and a preparation method thereof, in particular to an anthracene-based derivative and a preparation method thereof. The method for synthesizing anthracene-based derivatives of the present invention takes o-dimethylbenzene and naphthalene boronic acid as starting materials, and undergoes bromination reaction, Suzuki reaction, dehydration and cyclization, etc., to synthesize the final product. The compound prepared by the invention can be used as a blue light-emitting material in electroluminescent devices. Since its molecular structure contains an anthracene ring with stable performance, the stability of the light-emitting material is well solved, and its molecule does not contain nitrogen. , sulfur and other heteroatoms, prolong the service life of the luminescent material, so that the problem of the low service life of the blue luminescent material in the three-primary color luminescence is easily solved.

Description

technical field [0001] The invention belongs to the technical field of organic electroluminescence, and relates to a blue organic electroluminescent material and a preparation method thereof, in particular to an anthracenyl derivative and a preparation method thereof. Background technique [0002] With the rapid development of information technology, people put forward higher and higher requirements for information display technology. Since Tang C W and Vanslyke S A of Kodak Company in the United States produced the first organic electroluminescent device with excellent performance in 1987, organic electroluminescent displays have attracted great interest due to their many advantages. [0003] Organic electroluminescence (OEL) refers to the phenomenon that organic materials emit light when excited by electric current and electric field under the action of electric field. Organic light-emitting diodes (OLEDs) are a next-generation display technology that utilizes this phenom...
