Title:
ORGANIC LIGHT-EMITTING MATERIAL CONTAINING TETRAPHENYLBENZENE, PREPARATION, AND APPLICATION
Document Type and Number:
WIPO Patent Application WO/2020/228359
Kind Code:
A1
Abstract:
The present invention relates to the field of organic optoelectronic materials, and disclosed are an organic light-emitting material containing tetraphenylbenzene, preparation, and an application. The organic light-emitting material containing the tetraphenylbenzene has a structural formula as shown in formula I, wherein R1 is an aromatic nucleus derivative electron-donating group, and R2 is an aromatic nucleus derivative electron-withdrawing group. A preparation method therefor comprises: using 1,4-dibromo-2.5-terphenyl and R2-substituted phenylboronic acid as raw materials, and obtaining an aromatic nucleus compound containing the R2 by means of a Suzuki reaction; then, under the action of a tetrakispalladium catalyst, performing reaction on the aromatic nucleus compound containing the R2 and R1-substituted phenylboronic acid or borate, and obtaining the organic light-emitting material containing the tetraphenylbenzene. The organic light-emitting material containing the tetraphenylbenzene has the features of efficient solid-state light-emitting and double polarity, and can be used for preparing an organic electroluminescent device which is high in efficiency, low in roll-off degree and non-doped with blue light.
