摘要: We have demonstrated that, by changing the substituent groups on dithieno[2,3-d:2′,3′-d′]benzo[1,2-b:4,5-b′]dithiophene (DTBDT), one could effectively and rationally tune energy levels, optical band gaps charge transporting properties, etc. of DTDBT derivatives (DTBDTs) their conjugated polymers (CPs) diketopyrrolopyrrole (DPP) derivatives.
