Abstract

New diketopyrrolopyrrole (DPP)-containing conjugated polymer such poly (benzothieno[3,2-b]benzothiophene-2,5-bis(2-octyldodecyl)-6-(thiophen-2-yl) pyrrolo [3,4-c]pyrrole-1,4(2H,5H)-dione) was successfully synthesized via Horner-Emmons condensation. The polymer showed a low bandgap energy (Eg = 1.56 eV) in a film state. The polymer also exhibits good solubility in common organic solvents and good self-film-forming properties. The semiconducting properties of the polymer synthesized herein were evaluated in organic thin film transistors (OTFTs). The polymer exhibits charge carrier mobilities as high as 3.0 × 10-3 cm2V-1s-1 (I on/off = 105) after thermal annealing at 200°C for 10 min, which is three times higher than that of thin film transistor made of the pristine film.
