Multilayer films of poly(3-octylthiophene)-arachidic acid were prepared and characterized using ellipsometry, microscopy, UV-visible absorption and capacitance measurements. When doped with iodine or SbCl5 gas the conductivity of the films increased by a factor of 105 up to 2 × 10−4S cm−1. Removal of the dopant from the films was quite rapid in dynamic vacuum and in air.
