The first oligo(3-methoxythiophene) films that naturally appeared gold-like and lustrous green color tones were prepared by the cyclic potential-sweep electropolymerization of 3-methoxythiophene. Control experiments and optical/structural analyses showed that the films consisted of the edge-on and face-on lamella structures of the oligomers, and that the former structure contributed to the development of gold-like luster. Also, it was suggested that the action of the cyclic potential sweep was to preferentially destroy the face-on lamella, highlight the effect of the edge-on lamella, and develop gold-like luster.
