The invention discloses a synthesis method of a 5, 10-dihydroindolo [3, 2-b] indole derivative, the method comprises the following steps: mixing a 2-((2-halogen phenyl) ethynyl)-N, N-dimethylaniline derivative (II), N, N-di-tert-butyl diazacycloketone (III), a palladium catalyst, a monophosphine ligand, alkali and a first organic solvent, and carrying out a diamidation reaction under the protection of inert gas to realize the synthesis of the 5, 10-dihydroindolo [3, 2-b] indole derivative(I). The method is easy to operate, mild in reaction condition and high in reaction yield, and the synthesized 5, 10-dihydroindolo [3, 2-b] indole derivative can be used for preparing an organic light-emitting device.
