Document Type and Number:
WIPO Patent Application WO/2018/014389
Kind Code:
A1
Abstract:
Provided are a light-emitting material, a preparation method thereof and an organic light-emitting diode using the light-emitting material. The light-emitting material is in formula (I), and the light-emitting material can be applied to small molecule organic light emitting diode. The preparation method of the light-emitting material is as follows: utilizing Bromophenyl Thiophenol and 2-fluoro-4-bromobenzonitrile as starting materials, obtaining an intermediate product of the light-emitting material through a series of reactions, and finally obtaining the light-emitting material through Ullmann reaction or Suzuki reaction. A light-emitting layer of the organic light-emitting diode contains the above-mentioned light-emitting material, which has higher luminous efficiency and stability.
