| Outline of Final Research Achievements |
We previously found that the high-molecular weight oligomer of 3-methoxythiophene exhibited a gold-like luster. In this study, the effect of dopant and substituent on the optical and structural properties were firstly investigated in order to establish the basis of the gold-like color developing mechanism. The results showed that the film was colored red gold or blue gold dependent on the dopant type. The glossiness of film was also dependent on the type of dopant. The change in the substituent led to a change in the lamellar interlayer distance in the lamellar crystallites formed in the film, causing the change in the chromaticity and glossiness of the film. Secondly, the blend films of the oligomer and polyester were successfully prepared without losing the gold-like luster.
