Title:
LIGHT-EMITTING MATERIAL, PREPARATION METHOD THEREFOR AND ORGANIC LIGHT-EMITTING DIODE USING LIGHT-EMITTING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/014408
Kind Code:
A1
Abstract:
Provided are a light-emitting material, a preparation method therefor and an organic light-emitting diode using said light-emitting material. The light-emitting material has a single structure, a definite molecular weight, a better solubility and film forming property, and a stable film morphology; it has a very high decomposition temperature and a lower sublimation temperature, being easily sublimated into a high-purity light-emitting material, and can be applied to a small molecule organic light-emitting diode. In the preparation method of the light-emitting material, an intermediate of the light-emitting material is obtained by means of a series of simple reactions by using p-bromothiophenol and 2-fluoro-4-bromobenzonitrile as starting materials, and finally, the light-emitting material is obtained by means of an Ullmann reaction or a Suzuki reaction. The steps are simple, and the yield is high. The organic light-emitting diode and a light-emitting layer comprise the light-emitting material and have a higher luminance and stability.
