The organic light emitting material and the preparation method and application

One kind benzotriazine series of pyrazine derivatives prepared luminescent material, comprising: ethanol as solvent, acetic acid as catalyst and a series of three benzene derivative structural unit of the pyrazine series, Synthesis the method is simple, low toxicity of the solvent, ease of processing, purification easy, relatively low cost, particularly in the device structure can improve the efficiency and lifetime of the device itself, is a very promising class of organic electroluminescent material.
