Photostructuring and Consecutive Doping of an Anthracene-Containing Polymer: A New Approach Towards Conductive Patterns

Producing patterns by changing the dopability of polymers is the approach presented here. The authors produced the image shown on an anthracene-based polymer film by illumination of the film through a mask, which destroys the dopability and conductivity. Exposure of the film to iodine renders the rest of the film dark and more conductive by ten orders of magnitude.
