Robust and Reproducible Photo-Responsive Transistors based on a Dual Acceptor-containing Low Bandgap Polymer |
| 초록 |
Low bandgap pTTDPP–BT polymers consisting of electron−rich thienothiophene, electron−deficient diketopyrrolopyrrole, and benzothiadiazole units were synthesized. Phototransistors have been fabricated using ambipolar-behaving pTTDPP–BT polymers as active channel materials. The photo−responsive properties of the pTTDPP–BT phototransistors were investigated as a function of the annealing temperature. As−spun pTTDPP–BT phototransistors exhibited low hole and electron mobilities, which resulted in low photocurrent detection due to the limited transport of the photo−generated charge carriers. Thermal annealing of the polymer films resulted in a significant increase in the carrier mobilities and thus significantly improved photo−responsive properties. |
