摘要（英）：

The invention discloses an electron donor compound 1,2-bis((E)-(4-bromophenyl)diazenyl)acenaphthylene and a preparation method therefor. The preparation method comprises the following steps: (1) reacting acenaphthequinone and parabromophenylhydrazine to generate (1E,2Z)-1,2-bis(2-(4-bromophenyl)hydrazono)-1,2-acenaphthene; and (2) oxidizing the (1E,2Z)-1,2-bis(2-(4-bromophenyl) hydrazono)-1,2-acenaphthene to generate the 1,2-bis((E)-(4-bromophenyl)diazenyl)acenaphthylene. The preparation method for the 1,2-bis((E)-(4-bromophenyl)diazenyl)acenaphthylene is easy and feasible, yield and purity are high, industrialization is facilitated, photoelectric activity is improved remarkably. If the 1,2-bis((E)-(4-bromophenyl)diazenyl)acenaphthylene is used as a photovoltaic cell donor material, the photoelectric conversion efficiency of the photovoltaic cell can be remarkably improved surely, and in a preparation process, an intermediate, namely (1E,2Z)-1,2-bis (4-bromophenyl)hydrazono)-1,2-acenaphthene also has good photoelectric activity.
