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.
我们已经证明,通过改变二噻吩并[2,3- d:2',3'- d ']苯并[1,2- b:4,5- b ']二噻吩(DTBDT)上的取代基,有效,合理地调整DTDBT衍生物(DTBDT)及其共轭聚合物(CP)和二酮吡咯并吡咯(DPP)衍生物的能级,光学带隙和电荷传输性质等。
