In this presentation we report the development of novel semiconductors for mechanically flexible and more ductile transistors, electrochemical transistors, and the corresponding circuits. Particularly, we show that “ultra-soft” semiconducting polymer films can be achieved by introducing softer block units into the structure and/or modifying the film morphology to enhance porosity. Thus, we show that polymers comprising NDI or DPP units can efficiently transport charges, as accessed by TFT and OECT measurements, while being stretch to as much as &gt;100%. Furthermore, by manipulating the device architecture, building blocks circuits such as invertors, NOT, NOR, and NAND based on these devices were demonstrated exhibiting unprecedented performance (gain &gt; 150, stability &gt; 50000 operating cycles) and good mechanical flexibility.
