A self-doped conducting polymer S-PEDOT monolayer was prepared by co-spreading with amphiphilic amine molecules on water. The mother solutions of S-PEDOT and amphiphiles were prepared with water or THF solvents, respectively. Mixed solutions were prepared by mixing these two solutions at target ratios and were spread on a water surface in a Langmuir trough. Didodecyl amine (DDA) was used as amphiphilic molecules. The floating monolayers could be transferred onto a solid substrate. The mainchain orientations in the transferred films were evaluated by polarized absorption spectroscopy. Current(I)–voltage(V) measurements of the films were performed to elucidate electrical characteristics. Voltage (V)–time (t) measurements of the films were performed to observe phase delays in the electrical response.
