The present invention provides a light emitting material, a manufacture method thereof and an organic light emitting diode using the light emitting material. The structure is unitary, and the formula weight is determined, and the better solubility and film formation are provided, and the thin film status is stable; it possesses a very high decomposition temperature and a lower sublimation temperature, and is easy to sublime to be light emitting material of high purity, and can be applied for small molecule organic light emitting diode. In the manufacture method of the light emitting material according to the present invention, p-bromophenol and 4-Bromo-2-fluorobenzonitrile are employed to be starting materials, and the intermediate of the light emitting material is obtained with a series of simple reactions, and finally, the light emitting material is obtained with Ullmann reaction or Suzuki reaction, and the steps are simple and the production is high.
