Isoindigo (IID) and diketopyrrolopyrrole (DPP) are two of the most important acceptor units for high mobility donor-acceptor (D-A) conjugated polymers. We have design and synthesized IID- and DPP-based novel acceptor units such as isoindigo[7,6-g]isoindigo (DIID) as well as some polycyclic aromatics, e.g., dithienocarbazole (DTC) and dithienonaphthodithiophene (DTNDT), as donor units. The polymers based on IID and DTC are promising donor materials for polymer solar cells (PSCs), and those based on DIID displayed ambipolar transport properties as evaluated with organic thin-film transistors (OTFTs). We also found that 1,2-bis(3,4-fluorothien-2-yl)ethene was very reactive in direct arylationpolycondensation, and its polymers with DPP exhibited great ambipolar transport properties. Electron and hole mobilities up to 5.86 and 3.40 cm2/V×s, respectively, have been achieved.
