摘要：

A comparison of doping and photoinduced IRAV spectra of conjugated polymers with more complex structures is presented. Differences in behavior regarding the comparison of p- and n-doped states of different materials were observed. In contrast, a comparison between doped and photoinduced IRAV spectra often show a similar band pattern. Our results do not agree with the predictions given by theoretical descriptions, which were developed for simpler structures. From these theories, the same IRAV pattern for p- and n-doping, but differences to photoinduced IRAV should be expected. (C) 2001 Elsevier Science B.V. All rights reserved.
