Poly[quinacridone-alt-quaterthiophene] (PQCQT) was synthesized, using a Suzuki coupling reaction, to investigate the potential of quinacridone derivatives as organic semiconductors in organic fieldeffect transistors (OFETs) and circuits. A PQCQT film annealed at 150 °C yielded quite high field-effect performances, including a hole mobility of 2.0 × 10-2 cm2/(Vs). In addition, to confirm the feasibility of using PQCQT in high-voltage circuit applications, electrical behaviors of PQCQT-based OFETs were described by extracting the model parameters of the industry standard compact Berkeley short-channel IGFET model. From the developed OFET model parameter set, we successfully evaluated the circuit operation of a p-type organic inverter with a frequency of 45.5 kHz in an 80 V supply condition.
