Abstract

Diketopyrrolopyrrole (DPP)-based conjugated polymer (P(DPP-BDT)) containing benzodithiophene (BDT) was successfully synthesized via Stille coupling reaction. The synthesized polymer shows good solubility in common organic solvents and good selffilm- forming properties. The electrical properties of the polymer were evaluated in organic thin film transistors (OTFTs). The TFT made of pristine P(DPP-BDT) film exhibits good carrier mobility of 0.38∼0.40 cm2 V-1 s-1 (Ion/off = 106, Vth =-9 V), which is close to the mobility of TFT made of the thermally annealed film.
