[Abstract]
We demonstrate high-performance flexible polymer OFETs with P-29-DPP-SVS in various geometries. The mobilities of TG/BC OFETs are approximately 3.48 ± 0.93 cm2/V s on a glass substrate and 2.98 ± 0.19 cm2/V s on a PEN substrate. The flexible P-29-DPP-SVS OFETs exhibit excellent ambient and mechanical stabilities under a continuous bending stress of 1200 times at an R = 8.3 mm. In particular, the variation of μFET, VTh and leakage current was very negligible (below 10%) after continuous bending stress. The BG/TC P-29-DPP-SVS OFETs on a PEN substrate applies to flexible NH3 gas sensors. As the concentration of NH3 increased, the channel resistance of P-29-DPP-SVS OFETs increased approximately 100 times from ∼107 to ∼109 Ω at VSD = −5 V and VGS = −5 V.
