(a) UV-vis absorption spectra of PEDOTF8 with different molecular weights in dichloromethane. (b) UV-vis absorption spectra of PEDOTF8 films with different molecular weights. (c) UV-vis absorption spectra of PEDOTF8 (M n = 1800 and M n = 95000) in dichloromethane (solid line) and as a film (dotted line). Redshifts are shown by arrows. (d) Fluorescence spectra of PEDOTF8 with different molecular weights in dichloromethane. Photograph of PEDOTF8 in dichloromethane under UV irradiation. M n = 1800 (left) and M n = 95000 (right).
