Abstract: The present invention relates to efficient synthetic method of 1,3,5-tris (N-Phenylbenzimidazole) Benzene and pertains to the field of synthesis of organic light-emitting materials. The method and process of the patent are as following: 1,3,5-tris (N-Phenyl-N Phenylammonium) Benzamide is treated by shrinking agent but no high temperature required, and then high purity product can be reached after raw material dissolved. The reaction only takes a few minutes and through recrystallization the purity can be over 99%, and then the material with stable crystal phase reached after sublimation step. The method introduced by the present patent is easy to operate, and with high in yield and purity, which adapt industrial production and has important significance for the industrialization.
