WebMay 13, 2024 · The dichroic ratio (DR) of the P3HT film reflected by UV–vis spectra can reach as high as 7.1, which is much larger than the value treated by thermal annealing. Moreover, the excitation bandwidth W, indicating the effective conjugation length and molecular order, shows significant anisotropic features. Solvent used for solution …
WebNov 1, 2015 · The FTIR spectra also indicated the conjugation length of the P3HT polymer chain. The conjugation length is based on the results of the intensities ratio of the symmetric ring stretch at 1456 cm −1 to the asymmetric ring stretch at 1510 cm −1 (I sym /I asym) [25]. Longer conjugation length in the polymer backbone results in smaller I sym …
