The patterning of polymer‐based semiconductors, conductors, and insulators using photoresists is compromised because of the chemical vulnerability of polymers towards etching and photopatterning steps. Here an approach to the preparation of polymer LEDs using soft lithography techniques based on elastomer stamps is presented. The Figure shows line‐shaped LEDs produced by microcontact printing.
