We report the synthesis of a new star-shaped π-conjugated oligomer, BDT(DPP)4, containing a benzodithiophene core and four diketopyrrolopyrrole arms. The thermal, electrochemical and opticalproperties are characterized and the results complemented by computational studies. The utility of the molecule is demonstrated in both solarcell and field-effect transistor devices. In the former, BDT(DPP)4 displays
