We report the synthesis of two new organic semiconductors based on benzo[2,1-b:3,4-b′]dithiophene-4,5-dione and benzo[2,1-b:3,4-b′]dithiophene end-capped with dibutyl-aminostyryl groups. Theirs optical and electrochemical properties in solution were investigated by UV–visible absorption and cyclic voltammetry and compared to their analogs without amino groups.
