The invention discloses a method for synthesizing 5,10-indolino[3,2-b]indole derivatives, comprising the following steps: 2-((2-halophenyl)ethynyl)- Mix N,N-dimethylaniline derivative (II), N,N-di-tert-butyldiazepine (III), palladium catalyst, monophosphine ligand, base and first organic solvent, in an inert Under the protection of gas, a bis-amination reaction is carried out to realize the synthesis of 5,10-indolino[3,2-b]indole derivatives (I). The method of the invention has simple operation, mild reaction conditions and high reaction yield, and the synthesized 5,10-indolino[3,2-b]indole derivatives can be used for preparing organic light-emitting devices. |
