Highly stable doping of a polar polythiophene through co-processing with sulfonic acids and bistriflimide.

ABSTRACT: Doping of organic semiconductors is currently an intensely studied field, since it is a powerful tool to optimize the performance of various organic electronic devices, ranging from organic solar cells, to thermoelectric modules, and bio-medical sensors. Despite recent advances, there is still a need for the development of highly conducting polymer:dopant systems with excellent long term stability and a high resistance to elevated temperatures. In this work we study the doping of the polar polythiophene derivative p(g₄2T-T) by various sulfonic acids and bistriflimide via different processing techniques. We demonstrate that simple co-processing of p(g₄2T-T) with an acid dopant yields conductivities of up to 120 S cm^-1, which remain stable for more tha
