A new 1,4-diketopyrrolo[3,4-c]pyrrole(DPP)-based molecule (I) was designed and successfully synthesized with 2,2'-bithiophene as starting material via bromination, selective debromination, amination, alkylation, cyanation，condensation etc., and the product and precursors were confirmed by 1H NMR, 13C NMR, IR, MS and elemental analysis.Compound (I) shows good solubility in organic solvents, and an intense absorption between 530-700 nm.
