Flexible transistors and circuits based on dinaphtho-[2,3-b:2′,3′-f]thieno[3,2-b]thiophene (DNTT), a conjugated semiconductor with a large ionization potential (5.4 eV), are reported. The transistors have a mobility of 0.6 cm2 V−1 s−1 and the ring oscillators have a stage delay of 18 µs. Due to the excellent stability of the semiconductor, the devices and circuits maintain 50% of their initial performance for a period of 8 months in ambient air.
