Low-operating-voltage flexible organic thin-film transistors with high thermal stability using DPh-DNTT and SAM gate dielectrics are reported. The mobility of the transistors are decreased by 23% after heating to 250°C for 30 min. Furthermore, flexible organic pseudo-CMOS inverter circuits, which are functional after heating to 200°C, are demonstrated.
