A novel synthetic strategy of thienothiophene-benzotriazole-based polymers for field-effect transistor applications |
| 초록 |
Thienothiophene-benzotriazole-based polymers were systematically designed and synthesized. The backbone planarity was increased by conformational locks (F···S, F···H–C, and C–F···πF) and solubility was increased by siloxane-terminated side chains. The polymers were utilized as active layers in organic field-effect transistors, and the effects of thermal annealing on the crystallinity of polymers and their electrical characteristics were studied. Octyl-PTTBTz-F showed a hole mobility of up to 4.2 × 10-3 cm2V-1s-1 with enhanced molecular orientation but it did not dissolve well in common organic solvents. The Si-PTTBTz polymer showed good solubility but inferior device performance with a hole mobility of up to 2.2 × 10-4 cm2V-1s-1. The rationally designed Si-PTTBTz-F, which contains both conformational locks and siloxane-terminated side groups, exhibited a superior hole mobility of 0.11 cm2V-1s-1 and good solubility in common organic solvents. |
