Abstract: Thienothiophenes are essential components for the development of effective organic semiconductors. This study is devoted to the synthesis of novel arylamine derivatives of benzothieno[3,2-b][1]benzothiophene (BTBT) and investigation of their optical and thermal properties. For this purpose, the Buchwaldt–Hartwig reaction was used to couple 2,7-dibromo-BTBT with various arylamines. The fluorescence quantum yield of the resulting molecules decreased from 60 to 16%, as the complexity of the amine moiety increased. The materials synthesized exhibit relatively high glass transition temperatures and thermal stability, which suggests potential applications in organic electronics.
