Abstract: Photocurable compositions that combine redox-active semiconducting organic polymers with photocurable organic molecules are provided. Upon exposure to radiation, the photocurable compositions form ion-permeable, electrically conductive crosslinked organic films that can be used as conducting channels in n-channel or p-channel organic electrochemical transistors, including vertical organic electrochemical transistors (vOECTs). The vOECTs can be incorporated in complementary electronic circuits.
