Abstract

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 the energy levels, optical band gaps and charge transporting properties, etc. of the DTDBT derivatives (DTBDTs) and their conjugated polymers (CPs) and diketopyrrolopyrrole (DPP) derivatives.
