| abstract |
The invention discloses a 2,2'-diaryl-3,3'-bidithiophene derivative, a synthesis method and an application thereof. The derivative of the present invention is obtained by Suzuki coupling reaction of 2,2'-dibromo-3,3'-dithiophene and aryl borate substrate Ar-B(OH) 2 ; wherein: the Ar is phenyl, substituted phenyl, 1-naphthyl, 2-naphthyl or anthracenyl. They have good optical properties, and can be used as organic small molecule optoelectronic materials, and can be applied in the fields of organic dyes, dye-sensitized solar cells, organic light-emitting diodes, organic field-effect transistors, and organic semiconductor materials. |
