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.

Abstract: An attachable article, e.g., a wristband or armband, includes a dynamically flexible electronic display disposed on a flexible substrate that is bendable or conformable to a user's wrist or other curved surface, and that enables images to be displayed in a manner that makes these images easily viewable to the user. The flexible substrate is supported to limit the bending motion of the flexible electronic display within the display's tolerance limits. Additionally, the flexible substrate may be incorporated into a flexible support having any of various clasping mechanisms and sensors capable of detecting movement, orientation, forces, acceleration, and other user movements so that user manipulation of the article causes a change in the presentation of content on the flexible display and/or may serve as a user input to cause the attachable article to perform one or more actions.
