A high-molecular-weight conjugated polymer consisting of alternating TIPS-substituted benzo[1,2-b: 4,5-b'] dithiophene (BDT) and diketopyrrolo[3,4-c] pyrrole (DPP) was synthesized by Suzuki cross-coupling and characterized for use in high performance OPVs. Good structural order, self-assembly in spun-cast films, and carrier mobility were observed. PTIPSBDT-DPP showed an OFET hole mobility of up to 0.12 cm(2) V-1 s(-1). Power conversion efficiencies of up to 8.0% were demonstrated for OPV devices.
